5.1 INTRODUCTION

In chapters 3 and 4, we have learnt, that homonuclear diatomic molecules or molecules having zero permanent dipole moment or oscillating dipole moment zero, do not show microwave and infrared spectrum, i.e., rotational and vibrational spectra are not observed; hence it becomes difficult to study their molecular structure. ...
