DESCRIPTION:Much of our research focuses on understanding the behaviour of
  individual molecules when they become energised following absorption of l
 ight or collision with an electron\, both very common processes.  Advancin
 g our knowledge of such molecular behaviour has widespread applications in
  areas including atmospheric chemistry\, astrochemistry\, industrial proce
 sses\, analytical instrumentation\, molecular structure determination\, an
 d molecular synthesis.  Usually\, the energised molecules undergo a variet
 y of fragmentation processes.  The basic physics of a fragmentation proces
 s determines the speed of each fragment and the direction in which it flie
 s away from the other fragments\, and if we can measure these speeds and d
 irections then we can ‘reverse engineer’ the process to learn about th
 e underlying physics.  We have recently developed a new tool for recording
  this information\, in the form of the Pixel Imaging Mass Spectrometry (PI
 mMS) camera.  By some measures the fastest camera in the world\, the PImMS
  camera allows us to detect individual molecular fragments with a time res
 olution of nanoseconds\, and is now being used around the world in a varie
 ty of experiments in the areas described above.  I will present some of th
 e science underlying the development of the camera\, and will also highlig
 ht some of the new science made possible by the PImMS technology.\n\nClair
 e Vallance is a Professor of Physical Chemistry in the Department of Chemi
 stry and Tutorial Fellow in Physical Chemistry at Hertford College\, Unive
 rsity of Oxford.  She has a variety of research interests\, including chem
 ical reaction dynamics\, applications of velocity-map and spatial-map imag
 ing to mass spectrometry\, and the development of laser spectroscopy techn
 iques for microfluidics and chemical sensing applications\, and is a co-in
 ventor of the PImMS ultrafast imaging camera.  In addition to her research
  activities\, Claire is active in a wide range of teaching and outreach ac
 tivities within the Department of Chemistry and Hertford College.\nSpeaker
