Comparison of the Temperature Effect on the π *← n and π *← π Electronic Transition Bands of NO3-(aq)
The effect of temperature on the π *← π transition band in the UV absorption spectrum of NO3-(aq) centered at 200 nm was studied in the range of (10...70) oC. The observed temperature independence was in contrast with the significant influence of temperature on the nitrate π *← n transition reported recently by us. However, taking into account the electronic states involved in both transitions, it was concluded that this finding was in accordance with our previous assumption that interconversion between spectrally distinct (with respect to π *← n band) nitrate species included the rupture/formation of hydrogen bond(s) in the hydration shell of the nitrate ion.
