Abstract
The rotational spectra of two isotopologues of the tert-butylalcohol–dimethylether molecular complex have been measured with the pulsed jet Fourier transform microwave technique. In the complex, tertbutylalcohol acts as a proton donor. The H?D isotopic substitution of the hydroxylic hydrogen participating in the O–H O hydrogen bond produces an increase of the B and C rotational constants, according to the shrinkage of the O O distance of 5.5 mÅ, underlying and sizing the associated Ubbelohde effect.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
