' INTRODUCTION
NaNO3 is utilized in many chemical and industrial processes, and
also utilized as an energetic material in explosives. It is important to
understand the factors that enable NaNO3 to function as an
explosive and to develop methods to easily, remotely detect it.1À3
Inthework here we utilize deep UV resonance Ramanspectroscopy
(UVRRS) to probe the nature of the NaNO3 electronic excited
states and their complex photochemistry.4,5
We find strong RR
enhancement of the NO3h stretching fundamentals, as well as
overtones, indicating that the excited state is displaced relative to
the ground state.6À10
