 Title: A SIMPLE FACTORIZATION SCHEME TO PREDICT IVR RATES IN MEDIUM-SIZED ORGANIC MOLECULES Creators: Pearman, Ryan; Gruebele, M. Issue Date: 1998 Abstract: Other factors being equal, it has long been assumed that the IVR rate will decrease as the symmetry of the molecule increases. Recently, Callegari, et al. observed no trend: increasing rates of IVR in a progression from s-triazine to pyrrole to benzene in the first CH stretching overtone bands. The simple factorization method previously $developed^{a}$ has been applied to these systems. Using an anharmonic normal mode basis set for off-diagonal matrix element calculations and the MFD $method^{b}$, good agreement for the linewidths of pyrrole and s-triazine are obtained with only one adjustable parameter.
