Figure 17.

High frequency region of the difference IR spectrum: irradiated Xe matrix of 2-chloro-6-fluorobenzoic acid (2C6FBA) minus as-deposited matrix. Bands that arise due to the photoproduced CO₂ (including its ¹³C isotopologue), CO, 2-chloro-6-fluorophenol (2C6FPh) and 3-fluoro-chlorobenzene (3FCB) are pointing up, while bands due to the reactant (cis conformer) are pointing down. The lower frequency region shown in this figure (<2000 cm⁻¹) was included to allow a faster comparison of the intensities of the bands with those presented in Figure 16.
