✦ Synopsis

Mean am litudes of vibration for methyl ketene and several of its isotopic molecules &ich include deuterium. P 5C and 150 substitutions are calculated. Some remarkable secondcry isotope effects are reported fbr nonbonded CC. CH and O&I distanoeg. The vibrational spectra of ketene [l, Z] and dimethyl ketene [3] are well known. Less spectroscopic work has been published for methyl ketene. The structure of this molecule has been determined from microwave studies [4,5], which were based on nine isotopic species of methyl ketene. The in-plane H atom of the CH3 group (atom 6) is cis to the CC0 chain of atoms. Also
