“…In this set-up, the reflectors were placed on circular holders which were hanging on a rectangular frame. The frame has a provision for "x" and "y" movements [21]. This reflector set-up was placed parallel to the cell body to benefit six times UV light passes through the gas cell.…”

“…The laser is operated at 10 Hz repetition rate and thus overall accumulated decay of precursor during 53 s photolysis is estimated to be 0.166 torr; that means efficiency is 38.6%. In other words, it's clear that dropping of 0.166 torr C 6 H 5 Cl is the lower limit for observing major photolysis products during first 53 s. More details of this quantitative analysis method can be found in the forthcoming article [21].…”

This chapter intends to cover the instrumentation of gas phase Fourier transform infrared spectroscopy (FT-IR), its recent advancement, and applications. The major focus have been given to the principle and data acquisition scheme of the repetitive mode measurement method of FT-IR spectrometer. The application of this spectroscopy in the isomeric identification of the methylated polycyclic aromatic hydrocarbons (MPAHs) and the conformational analysis of diols have been discussed. Furthermore, the application of the repetitive measurement mode of FT-IR combined with the UV laser in monitoring the atmospherically relevant photochemical reactions has been covered. In conclusion, this chapter briefly summarizes the current applications and discusses future applications of this technique in following drug degradation.
