A 2E''-X2A2' transition of NO3 trapped in solid neon.
NO(3) has been stabilized in a neon matrix at 4.3 K in sufficient yield for detection of the absorptions between 7000 and 10,000 cm(-1), which arise from vibronically allowed transitions from the ground state to levels of the A (2)E'' state. The results confirm and somewhat extend previous gas-phase observations for (14)N(16)O(3). Additional spectra are presented for six other isotopologues of NO(3), four of which possess C(2v) symmetry. The splitting patterns for these species support the previous assignments. Alternations in the spacings of the nu(4) progression are consistent with the occurrence of weak to moderate Jahn-Teller interaction in the A 2E state of NO(3).
