The univariant (1112g) saturation vapor pressure of liquid deuterium oxide (phase I1) with liquid deuterium sulfide (phase I2) in equilibrium with a gas phase (g) has been measured in a stirred titanium reaction vessel at 19 temperatures from 33.003 to 18.905°C and at total pressures from 2.4500 to 1.7428 MPa. The univariant (hl1g) saturation vapor pressure of deuterium sulfide D-hydrate (phase h) in equilibrium with liquid deuterium oxide and a gas phase has been measured at 58 temperatures from 30.666 to 2.798°C and at pressures from 2.2959 to 0.11629 MPa. The maximum temperature for deuterium sulfide D-hydrate with a gas phase, the invariant quadruple point Q(h1112g), has been determined from the cut of the (h11g) and the (l112g) curves at temperature 30.770°C with standard error 0.0043°C and at pressure 2.3263 MPa with standard error 0.00018 MPa. The univariant (s111g) equilibrium of D-ice (phase s1) with liquid deuterium oxide and a gas phase containing deuterium sulfide has been measured at 11 temperatures from 3.8061 to 3.4540°C and at pressures between 0.00242 and 0.10542 MPa. The lowest temperature for stability of deuterium sulfide D-hydrate with liquid deuterium oxide, the invariant quadruple point Q(hs111g), has been determined directly at 3.3917°C with standard error 0.0009°C and at pressure 0.12364 MPa with standard error 0.000011 MPa. This quadruple point Q(hs111g) has also been defined by the cut of the (hl1g) and the (s111g) curves at temperature 3.3912°C with standard error 0.0006°C and at pressure 0.12363 MPa with standard error 0.000002 MPa. The deuterium sulfide - deuterium oxide gas mixture, represented by a Redlich-Kwong equation of state, has been used to evaluate the fugacities and compositions of the gaseous and liquid deuterium oxide phases for all equilibria. Raoult's law using fugacities has been used to evaluate the saturation mole fraction of deuterium oxide in liquid deuterium sulfide and the Henry's law constant for deuterium oxide solubility in liquid deuterium sulfide between 33.003 and 18.905°C. Data for the (I112g) and (s111g) equilibria have been accurately represented by simple two-parameter equations. Data for the (hl1g) equilibrium have required a model with seven significant parameters for proper representation between 30.666 and 2.798°C.
Isolation of H2S...ClF in a pre-reactive mixture of H2S and ClF expandedin a coaxial jet and characterization by rotational spectroscopy

The reaction between H2S and ClF was precluded and H2S...ClF isolated bya coaxial supersonic expansion of the gaseous components into the Fabry -Perot cavity of a pulsed-nozzle, Fourier-transform microwave spectrometer. The ground-state rotational spectra of seven isotopomers of H2S...ClF were analysed and gave in each case the spectroscopic constants 1/2(B(0)+C(0)), D(J), χ(aa) (Cl) and M(bb) (Cl). Interpretation of these constants revealed the complex to have a geometry of C(s) symmetry with the S...Cl-F nuclei collinear in the order shown, with the angle 180°-φ=84.2(4)° between the C(2) axis of H2S and the S...Cl-F axis, and with r(S...Cl)=2.857(3)?.
The structure of NH3*H2S and free internal rotation effects

The structure of NH3*H2S has been determined from microwave and radiofrequency spectroscopy of this complex and its deuterated isotopomers, using molecular beam electric resonance techniques.Rotational constants, electric dipole moments and nitrogen quadrupole coupling constants were obtained from the spectra.The molecule was found to have a linear, hydrogen bonded structure with the ammonia as the proton acceptor.The NS distance is 3.639 Angstroem, the root-mean-square angular deviation of the NH3 axis from the N-S axis is 24.6 deg and the H2S C2 axis is 40.5 deg from the N-S axis.Although the molecule is an asymmetric rotor, first-order Stark effects were observed for K = 1 rotational levels.These Stark effects are caused by torsional oscillations which are essentially ammonia monomer free internal rotation.Similar effects were observed for NH3*H2O and are reported here.
Photodissociation dynamics of H2S(D2S) following excitation within its first absorption continuum

The technique of H(D) atom photofragment translational spectroscopy has been applied to the photodissociation of H2S(D2S) following excitation at a number of wavelengths in its first absorption continuum.The respective bond dissociation energies were determined as D0(H-SH) = 3.90 +/- 0.03 eV and D0(D-SD) = 4.00 +/- 0.02 eV.The measured vibrational energy disposal in the partner ground state SH(SD) fragments and the product angular distributions support and extend the earlier results of van Veen et al. , while the deduced rotational andspin-orbit state population distributions in these fragments appear to be generally consistent with the recent measurements of Weiner et al. .We present a schematic adiabatic potential energy surface for the dissociative 1A'' excited state via which it is possibe to rationalize virtually all existing dynamical measurements relating to this fragmentation process.
Matrix Isolation Study of the Reaction of B2H6 with H2S: Spectroscopic Characterization of Mercaptoborane, H2BSH
Carpenter, John D.,Ault, Bruce S.
, p. 7913 - 7916 (1992)
Merged jet copyrolysis of mixtures of Ar/B2H6 and Ar/H2S followed by trapping in a cryogenic matrix has led to the formation, isolation, and characterization of mercaptoborane, H2BSH.Eight of the nine fundamentals of this molecule were observed, including the boron-sulfur stretching mode at 804 cm-1 ((11)B).Local density functional and normal-coordinate calculations were carried out to assist in assigning the observed fundamentals.The position of B-S stretching mode, compared to a range of known compounds, suggests single bond character for the B-S bond.Additional products were observed, including HBS, and suggests further reaction of H2BSH at high temperatures.A mechanism for the reaction is proposed.
