Study of the hindered internal rotation in 3-chlorophenol

Abstract The torsional OH and OD modes in the two conformations of 3-chlorophenol have been assigned by infrared and Raman spectroscopy. Assuming C 1 xC 2 rotational symmetry, we have computed the coefficients V 1 and V 2 for that symmetry by using three different procedures. As in the case of other chlorosubstituted phenols, the geometry of the group undergoing rotation is seen to depend on the isotopic exchanging.
