| Abstract: | Semi-empirical conformational analysis of five methanol +
ketone systems with a systematic study with the variation of the hydrogen bond
angle have been studied. The results of the conformational analysis are
compared with experimentally determined dipole moments of the five systems. The
ketones chosen for the present study are acetone, 2-butanone, 3-pentanone,
cyclohexanone and acetophenone. Conformational analysis is done using the PM3
semi-empirical Hamiltonian and the dipole moments are determined using
dielectric relaxation studies at microwave X-band frequency (9.97 GHz). Further
confirmation with previous 13C NMR chemical shift data is also
sought. |
