Figure 5

Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) analysis of 1,8-dihydroxynaphthalene (1,8-DHN) adsorbed on forsterite during UV irradiation at 80 K (A) and during heating (from 80 to 300 K) after UV irradiation (B). Inset: magnification of the peak at 2340 cm−1 due to CO2 stretching.
