Data: table, diagram

Energy/Wavelength range: 290 - 400 nm

Resolution: 

Temperature: 293 K

Temperature dependence: no

Pressure/Concentration: 0.00500, 0.0100, 0.0200, 0.0300, 0.0400, 0.0800, 0.120 M  nitrite

Comments: The UV decadic molar absorptivities of nitrite ion in water were determined between 290 and 400 nm in 2-nm 
increments. The measured maximum absorptivity of 22.93 M cm-1 at 354 nm is in agreement with previous results.
