Abstract
Abstract The nonrigidity of a series of aromatic aldehydes in very dilute solution is studied. This internal mobility consists of the rotation of the aldehyde group around the CC bond or of high amplitude jumps from one potential well to the another. The second type of movement becomes apparent in the FIR. The absorption peaks are connected with torsional oscillations of the aldehyde group in one of the potential wells. The lack of proportionality between the amplitude of the second dispersion peak and the integrated absorption suggests a particular type of intramolecular movement: torsional oscillations or rotational diffusion over possibly flattened potential energy barriers, depending on temperature and viscosity of the solvent.
