Abstract Double Resonance M odulation (DRM) microwave spectroscopy has been used to determine the complete substitution structures of 1,2,5-thiadiazole and 3,4-d2-1,2,5-thiadiazole. The 34S-, 13C- and 15N-species o f these two “parent” molecules were studied in natural abundance. The structure parameters o f the two parent forms agree to within ± 0.0005 Å and ± 0.02° with the following averaged values: Distances (in Å) S - N = 1.6296 C = N = 1.3270 C - C = 1.4167 C - H = 1.0805 Angles (in degrees) NSN = 99.44 SNC = 106.51 NCC = 113.77 CCH = 126.27 The new data confirm the earlier work on this substance, but the precision o f the structure parameters is improved by a factor of ~ 10. The apparent C-C bond length in the normal species is found to differ by ~ 0.001 A from that in the 3,4-d2-species. Vibrational contributions (⊿Ivib) to the effective changes of the moments o f inertia are determined for the sulphur atom and the near-axis nitrogen atoms as ⊿Ivib(S) = - 0.0017 μÅ2 and ⊿Ivib(N) = - 0.0035 μÅ2. Energy transfer through collisions has been exploited to overcome traditional difficulties in the identification o f high-J Q-branch transitions o f rare isotopic forms.

Collisional Energy Transfer

Collisional energy transfer between rotational levels of ethylene oxide C2H4O, its deuterated species C2D4O and carbonyl sulfide OCS, has been investigated by means of microwave-microwave four-level double resonance. The results are in agreement with collisional selection rules which can be predicted in the weak collision limit. Collisionally induced transitions up to ΔJ = 4 have been detected for C2D4O.
