The infrared spectra of 3-pentyn-2-ol, CH 3 C"CCH(OH)CH 3 , have been recorded as a vapour and liquid at ambient temperature, as a solid at 78 K in the 4000-50 cm Γ1 range and isolated in an argon matrix at ca. 5 K. Infrared spectra of the solid phase at 78 K were obtained before and after annealing
## Abstract The Raman spectra (3400β10 cm^β1^) of liquid and solid 3βmethylβ3βvinylcyclopropene, C~3~H~2~(CH~3~)CHCH~2~, and its isotopomer C~3~D~2~(CH~3~)CHCH~2~ were recorded. The temperature dependence of some band intensities and qualitiative depolarization ratios show that the thermodynamicall
