Picosecond measurements of the dissociation rates of the nitric oxide dimer v1=1 and v4=1 levels

Abstract

Direct picosecond measurements of the vibrational predissociation rates of the nitric oxide dimer excited to v=1 levels of the symmetric (ν₁=1870 cm⁻¹) and antisymmetric (ν₄=1789 cm⁻¹) N–O stretching fundamentals are reported. Lifetimes obtained are 880±260 ps for ν₁ and 39±8 ps for ν₄ excitations.
