✦ Synopsis

The purpose of this paper is to present simple ideas about two kinds of infrared bands which are not considered in classical text books, namely hot bands and PAPE bands. The presentation is limited to molecules with (C_{3 v}) symmetry. PAPE bands are parallel bands with a perpendicular structure and belong to the (A_{1}+A_{2}) vibrational symmetry. Their different appearances are discussed Hot bands are very simple when the lower state has an (A_{1}) vibrational symmetry. We concentrate on the case where it has an (E)-type symmetry. Many examples of actual bands are quoted. c. 1993 Academic Press, Inc.
