Malik, J.A. Joens Title: Temperature dependent near-UV molar absorptivities of glyoxal and gluteraldehyde in aqueous solution Journal/Source: Spectrochim. Acta Part A: Molecular and Biomolecular Spectroscopy, 56, 2653-2658, (2000); doi:10.1016/S1386-1425(00)00311-5 Data: Energy/Wavelength range: > 200 nm Resolution: Temperature: 278 - 343 K Temperature dependence: yes Pressure/Concentration: Phase: aqueous solution pH: Comments: Molar absorptivities have been determined for glyoxal and gluteraldehyde in aqueous solution. Absorptivities are reported at eight temperatures in the range 5–70°C for wavelengths greater than 200 nm. Author to whom correspondence should be addressed: (e-mail address):
