6. 16 O12 C32 S is a linear molecule. The bond lengths are rCO = 1.16Å rCS = 1.56Å and the observed fundamental vibrational frequencies are ν1 = 858.9 cm−1 stretch ν2 = 520.4 cm−1 bend
ν3 = 2062.2 cm−1 stretch.
(a) Obtain kCS , kCO , and kθ [rCO rCS ]−1 in dynes/cm.
(b) What are the amplitudes for C-O and C-S stretch in the ν1 fundamental level?
(c) What are the vibrational frequencies for 18 O12 C32 S?
