Pagination or Media Count:
High resolution electron energy loss and UV photoemission spectroscopies have been used to study the chemisorption of pyridine on clean Ag111 at T approx. 140K. Pyridine is weakly chemisorbed and undergoes a compressional phase transformation from a pi-bonded species to a more weakly bound, nitorgen-lone-pair bonded species. The molecular orientations of both chemisorbed phases are determined. Author
