DESCRIPTION:Speakers: Evan Robertson (La Trobe University)\nThe IR spectra
 l region is crucial to our understanding of atmospheric chemistry and phys
 ics. Firstly\, radiative processes associated with emission and extinction
  are fundamental to energy transfer and the IR region in particular is cen
 tral for materials at the moderate temperatures found in non-stellar envir
 onments such as this planet’s atmosphere. Secondly\, infrared spectrosco
 py is uniquely suited to remotely probing the properties of atmospheric mo
 lecules and aerosols. \n\nWe have employed the various facilities on the f
 ar IR beamline to advance understanding of atmospheric molecules such as H
 FCs and CFCs\, and also aerosols such as water ice nanoparticles found in 
 high altitude clouds.  Our studies of crystalline water ice particles have
  recently been extended to both amorphous ice and to deuterium enriched cr
 ystalline ice\, providing insights into fundamental questions about the wa
 ter vibrations in these phases. An overview will be presented.\n\nhttps://
