The Carbon dioxide is a linear molecule. Its vibrational motions comprise symmetrical stretching, bending and asymmetrical stretching and the frequencies are 4.02 x 1013 s-1, 2.00 x 1013 s-1, and 7.05 x 1013 s-1, respectively. (a) Explain in what region of the electromagnetic spectrum are these frequencies? (b) Compute the energy (in J) of each vibration. Which takes place most readily takes the least energy?
