WebA fluorescent probe for the monitoring of H2S levels in living cells and organisms is highly desirable. In this regard, near-infrared (NIR) fluorescent probes have emerged as a promising tool. NIR-I and NIR-II probes have many significant advantages; for instance, NIR light penetrates deeper into tissue than light at visible wavelengths, and it causes less … WebNov 9, 2024 · New infrared spectra are presented for H 2 S and four other sulfur-containing compounds, all thiols, at 10–140 K to aid in the study of interstellar and solar system ices. Infrared spectral changes on warming H 2 S and each thiol are described with an emphasis on the S–H stretching vibration at 2550–2525 cm −1 (λ = 3.92–3.96 μm) as it is in a …
