Table 1: The wavenumbers ( $\tilde\nu$ in cm^-1) of the most prominent peaks of the heterocycles with their assignments, used to monitor the UV photodestruction. $\nu$ denotes a stretching mode, $\beta$ is a bending mode and $\tau$ refers to a torsion mode. Taken from a Destexhe et al. (1994) and b Morrison et al. (1997).
