WebJan 1, 2004 · On NaY zeolite, the adsorption of H2S was claimed to be almost non-dissociative. IR spectroscopy is a tool of choice for these studies but unfortunately, molar extinction coefficient of SH vibration bands is extremely weak, and therefore detection of SH groups by IR spectroscopy and interpretation of the corresponding bands is rather tricky.
