- Nascent rotational quantum state distribution of NaH (NaD) from the reaction of Na*(42P) with H2, D2, and HD
-
The nascent rotational quantum state distributions of NaH and NaD products resulting from the reactions of Na*(42Pj) with H2, D2, and HD have been determined using the laser pump-probe technique.We have observed a bimodal rotational distribution with a minor component peaking at low J and a major component peaking at high J.We have observed no evidence for a kinematic isotope effect on the product distribution.Our results are consisent with a model wherein the reaction occurs predominantly on the attractive 2B2 potential energy surface in near C2v geometry with the rotational distribution being determined late in the exit channel.

- Hydrogen diffusion in NaH as derived from isotope exchange experiments
-
We report on hydrogen-deuterium-exchange experiments on NaH probed by thermogravimetry. From the measurements a diffusion parameter of deuterium in NaH of D=1.1× 10-17 m2 /s at 523 K is derived. The activation energy of tracer diffus

- Spectroscopy of the NaH, NaD, KH, and KD X 1Σ+ ground state by laser excited fluorescence in a high frequency discharge
-
By laser excited fluorescence of the hydrides obtained in a discharge, the ground state vibrational levels of NaH, NaD, KH, and KD, have been observed up to v = 15, 20, 14, and 16, respectively , instead of v = 8,2 , 4, and 4 by conventional spectroskopy.Experimental values of Gv , Bv , and Dv are obtained.Spectroscopic parameters and RKR potential curves are calculated.In NaH and NaD, a comparison can be made with ab initio calculations.
