Notes. Thevalues are taken from the HITRAN 2012 spectroscopic database (Rothman et al. 2013). Upper and lower state “global” quanta are described using the HITRAN notation (Rothman et al. 2005): v1 v2 v3 v4 n C, where vj is the quantum number associated with the normal mode of vibration j, n is a multiplicity index and C (=A1,A2,F1,F2, and E) is the symmetry. Upper and lower state “local” quanta are described using the Brown et al. notation (Brown et al. 2003): J C α, where J is the quantum number associated with the total angular momentum excluding nuclear spin, C (=A1,A2,F1,F2, andE) is the symmetry and α is a counting integer for levels of the same J and C; the values are incremented in order of increasing energy.
