High and Moderate Resolution Infrared Spectroscopy of Diiodomethane


EMSL Project ID
16709

Abstract

We will record high (0.002 cm-1) and moderate (0.112 cm-1) resolution infrared spectra of diiodomethane. Diiodomethane is a trace compound found in the troposphere and is thought to be a sink for atmospheric iodine. The moderate resolution spectroscopy will be performed to determine the infrared abosorption cross section of the molecule. This information will be useful for those researchers trying to detect this molecule in the atmosphere. The high resolution spectroscopy will be performed to determine the structure and vibrational force field of the molecule.
