Abstract
Abstract The ir and Raman spectra of liquid and solid 2-cyclopenten-1-one have been measured. From these measurements, it has been ascertained that the molecule undergoes two phase transitions in the solid state, The ring-puckering motion, around 100 cm −1 , seems to be responsible for the molecular disorder in the solid state above 123 K. At this temperature, crystals of 2-cyclopenten-1-one are dichroic and centrosymmetric and have a unit cell of C 2 h symmetry.
