Abstract
NID-IR is a two-colour laser technique for recording IR spectra mass selectively. In contrast to the more well known ion dip approach, NID-IR measures the gain in ion current from a near zero background and is therefore potentially far more sensitive. It was first introduced by Fujii and $co-workers^{a}$ and was used to record IR spectra of several species in a supersonic molecular beam including phenol, fluorophenol, and acetylene. In preparation for studies of transient species, including organic free radicals and metal-solvent clusters, we have been exploring the mechanism and limitations of NID-IR spectroscopy. This talk will describe the technique and will summarise our latest findings from a series of studies of organic molecules, particularly substituted aromatics.
