✦ Synopsis

The anomalously large splitting and low intensity of vas(NO2) in solid 3,3-bis(nitratomethyl)oxetane, O(CH2)2C(CH2ONO2)2, is attributed to the effects of vibrational coupling based on a variable temperature study of the internal modes. In acetone-d6 solution conformational isomer equilibria involving the 49NO2 groups appear to exist that are manifested in v,, (NO2). This compound indicates that both isomerization and vibrational coupling should be kept in mind when using v,,(NO2) to obtain structural information on nitrate esters.
