Foreword

The interaction of electromagnetic (EM) radiation with molecular systems gives rise to quantized transitions between the electronic, vibrational and rotational molecular energy states which may be observed by UV/visible and infra-red absorption spectroscopies at frequencies above about 1 THz (1012 Hz). These quantum spectroscopies for molecules in the gaseous, liquid and solid states form a large part of physical chemistry and chemical physics. However, if one asks a fellow scientist “what happens when EM radiation in the range 10–6
