The SNO− and OSN− anions are shown in this work to be very stable negatively charged species in line with other recent work [T. Trabelsi et al., J. Chem. Phys. 143, 164301 (2015)]. Utilizing established quartic force field techniques, the structural and rovibrational data for these anions are produced. The SNO− anion is less linear and has weaker bonds than the corresponding neutral radical giving much smaller rotational constants.OSN− is largely unchanged in these regards with inclusion of the additional electron.The S–N bond is actually stronger,and the rotational constants of OSN− versus OSN are similar. The vibrational frequencies of SNO− are red-shifted from the radical while those in OSN− are mixed. OSN− has mixing of the stretching modes while the S–N and N–S stretches of SNO− are largely independent of one another. The ω3 stretches are much brighter in these anions than they are in the radicals, but the ω1 stretches are still the brightest.
