摘要：

Molecular ion calorimetry: A technique for measuring the heat capacity of an isolated gas-phase chromophore is presented and applied to the retinal protonated Schiff base (see picture). The potential use of this technique for studying barriers for internal rotations is discussed. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
