We report the results of a pulsed jet Fourier transform microwave spectroscopy investigation of the Ethylalcohol– Cyclobutanone molecular complex. The rotational spectrum has been assigned to one conformer in which the gauche species of ethylalcohol acts as the proton donor to one sp2 lone pair of the carbonyl oxygen of cyclobutanone. After deuteration of the hydroxyl group involved in the hydrogen bond a 7–8 mÅ shrinking of the O O distance (Ubbelohde effect) has been quantified.

Abstract
We report the results of a pulsed jet Fourier transform microwave spectroscopy investigation of the Ethylalcohol– Cyclobutanone molecular complex. The rotational spectrum has been assigned to one conformer in which the gauche species of ethylalcohol acts as the proton donor to one sp2 lone pair of the carbonyl oxygen of cyclobutanone. After deuteration of the hydroxyl group involved in the hydrogen bond a 7–8 mÅ shrinking of the O O distance (Ubbelohde effect) has been quantified.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
