Microwave Spectrum of 2-Methylcyclohexanone.
The rotational spectrum of 2-methylcyclohexanone in the ground state has been observed in the frequency region from 5 to 18 GHz. Transitions having a-, b-, and c-dipole selection rules were all seen. The rotational constants of the ground states are A = 2875.2938(2), B = 1999.3393(1), and C = 1299.1896(1) MHz. These rotational parameters are consistent with a chair conformation of 2-methylcyclohexanone in which the methyl group is in the equatorial position. Copyright 2000 Academic Press.
