The proton Affinity of CS

Article abstract of DOI:10.1021/j100265a007

We have studied the reactivity of HCS(1+) ions with several molecules at 300 K using a SIFT apparatus.The measured rate coefficients for the proton-transfer reactions of HCS(1+) with C2H5OH and CH3SH are appreciable fractions of their respective collosional rate coefficients and from this we deduce that the proton affinity of CS is 188.2 +/- 1 kcal mol^-1.This value differs from the literature value by some 13 kcal mol^-1 but is in close agreement with a very recent theoretical value.
