H2S · Ne
Two progressions were observed for each of the symmetric isotopomers (with H2S or D2S).
This doubling is attributed to an internal rotation motion of the H2S subunit within the
complex. For 20Ne · H232S, the wavenumber of the intermolecular stretching motion and
the force constant are 18.4 cm–1 and 0.252 N m–1 for IH=0 and 27.6 cm–1 and 0.566 N m–1
for IH=1, respectively.
