An effort to explain the ground state and excited state photophysics of pyrrole-2-carboxyldehyde (PCL) and its related compounds in ultraviolet–visible (UV–VIS) and infrared (IR) region has been reported in this paper. We have observed the mid-infrared absorption by using FTIR methods and obtained spectrum of PCL solid samples in the wavenumber region ranging from 450 to 4400cm −1 with resolution...
