Abstract
Abstract From Raman. IR and 35 NQR data and thermal analysis it is concluded that there are two polymorphic phases in solid methyl chloroacetate (M-MCA). The Raman and IR spectra of M-MCA have been studied for each of the two crystalline phases at ca. 80 K. The results of 35 Cl NQR measurements are found to be consistent with the vibrational spectra. Conformational properties of M-MCA are discussed and it is proposed that both cis and (probably) gauche isomers (in relation to the chlorine atom and carbonyl group) exist in the liquid phase and that the cis isomer remains in both crystalline phases.
