1. The problem statement, all variables and given/known data Consider a CO2 molecule, which is linear and has vibrational modes with frequency corresponding to 2565 cm-1 (an asymmetric stretch), 1480 cm-1 (a symmetric stretch) 526 cm-1 (bends). Sketch a curve showing how the constant volume heat capacity of CO2 gas varies with temperature and mark the values of plateaus. (Recall: the spacing between rotational levels is smaller than the spacing between the vibrational levels). 3. The attempt at a solution I don't have a clue where to start!
