science-softCon uv/vis+ photochemistry database; www.photochemistry.org; (C) science-softCon 2019 Substance: nitromethane Other Names: methane, nitro- Formula: CH3NO2 CAS-No.: 75-52-5 Study: uv absorption spectrum Authors: S. Nagakura Title: Ultra-violet absorption spectra and pi-electron structures of nitromethane and the nitromethyl anion Journal/Source: Mol. Phys., 3, 152-162, (1960); DOI: 10.1080/00268976000100171 Data: diagram Energy/Wavelength range: ~ 195 - 280 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas, aqueous solution pH: Comments: Besides the weak band at 270 nm, a strong band, which may be regarded as due to the longest wavelength Pi-->Pi* transition band, was observed at 198 nm in the gaseous state. Further, the absorption spectrum of nitromethane was measured in aqueous solutions with several different ph values, and a strong band was observed at 233 nm.
