Conformational stabilities of dicyclopropyl ketone determined from variable temperature infrared spectra of xenon solutions and ab initio calculations†
Abstract
The infrared (3500–40 cm−1) O, along with the Raman (3500–40 cm−1)
O bond over the two three-membered rings) and minor cis–trans
(Cs) form (C
O bond eclipsing the hydrogen atom on one of the rings) have been identified in the fluid phases. Variable temperature (−55 to −100 °C) studies of the
