The following states are included in this calculation: the ground state, $\nu_4$, $2\nu_4$, $\nu_5$, $2\nu_5$, $3\nu_5$, $\nu_4+\nu_5$, $2\nu_4+\nu_5$.
The vibrational levels are labeled as $V_4^{l_4}V_5^{l_5}$. The vibrational designations are as the following: 00 for $0^00^0$ ($^1$${\Sigma}$$_g$$^+$); 01 for $1^10^0$ ($^1$${\Pi}$$_g$); 02 for $0^01^1$ ($^1$${\Pi}$$_u$), 03 for $2^20^0$ ($^1$${\Delta}$$_g$), 04 for $2^00^0$ ($^1$${\Sigma}$$_g$$^+$), 05 for $1^11^1$ ($^1$${\Sigma}$$_u$$^+$), 06 for $1^11^1$ ($^1$${\Delta}$$_u$); 07 for $1^11^1$ ($^1$${\Sigma}$$_u$$^-$); 08 for $0^02^0$ ($^1$${\Sigma}$$_g$$^+$); 09 for $0^02^2$ ($^1$${\Delta}$$_g$); 10 for $0^03^1$ ($^1$${\Pi}$$_u$); 11 for $0^03^3$ ($^1$${\Phi}$$_u$); 12 for $2^21^1$ ($^1$${\Pi}$$_u$(II)); 13 for $2^21^1$ ($^1$${\Pi}$$_u$(I)); 14 for $2^21^1$ ($^1$${\Phi}$$_u$). The experimental measurements were reported by Lafferty et al. 1977, J. Mol. Spectrosc. {\bf 64}, 147; Deleon and Muenter 1987, J. Mol. Spectrosc. {\bf 126}, 13; Huet et al. 1991, J. Chem. Phys. {\bf 94}, 3407; Yu et al., 2009, Astrophys. 698(2) 2114-2120, 2009.


A vibrational transition dipole moment of 0.0358 D, which was determined for the $\nu_5$-$\nu_4$ difference band by Lafferty et al. (J. Mol. Spectrosc. {\bf64}, 147), was used for all the transitions because dipole moments for other bands are not available.
