A. Potier et al., RAMAN-SPECTROSCOPY OF THE HYDROGEN-BOND IN THE ASSOCIATES H2O-CENTER-DOT-HNO3 AND (HNO3)(2)NO3-CENTER-DOT- EVANS WINDOWS, Polish Journal of Chemistry, 72(2), 1998, pp. 292-301
The discontinuous shifts of Raman lines with the concentration between
500 and 2600 (-1) in solutions of HNO3-H2O and KNO3-HNO3 show the for
mation of the associates cm H2O . HNO3 and (HNO3)2 . NO3-. The study o
f the 2000-3600 cm(-1) range enhances the complexity of the OH' spectr
a with the occurrence of Evans windows, owing to the formation of hydr
ogen bonds in the two associates.
