(c) In the infrared spectrum of 12C16O a strong band is observed at 2143cm1 and a weak band at 4260cm1. Calculate: (i) The vibrational frequency, c and anharmonicity constant xe given that the centre of the fundamental band corresponds to c(12xc) and the centre of the first overtone band corresponds to 2e(13xe). (ii) The number of vibrational levels given that: vmax=1/(2xc)1 (iii) The bond dissociation energy in kJmol1 given that: vmax=e(vmax+1/2)exc(vmax+1/2)2 (iv) The force constant given that kf=42c2c2 [45marks]
