Notes. Multiple band assignments connect to several local maxima or shoulder features for one band. The error in the measured positions lies within 2 cm−1. (a)See Table 1. (b)The vibrational assignment is taken from Sandford & Allamandola (1993), where ν3 and ν8 are assigned to 2827 cm−1 and 1026 cm−1, respectively.
