Time-resolved Raman spectroscopy

The high costs associated with specialist ultrafast laser techniques can make their purchase prohibitive to many university research laboratories. However, centralised national and international research infrastructures hosting a variety of large scale sophisticated laser facilities are available to researchers. In Europe access to these facilities is currently obtained either via successful application to Laser Lab Europe (a European Union Research Initiative) [35] or directly to the research facility. Calls for proposals are launched at least annually and instrument time is allocated to the research on the basis of peer-reviewed evaluation of the proposal. Each facility hosts a variety of exotic techniques, enabling photoactive systems to be probed across a variety of timescales in different dimensions. For example, the STFC Central Laser Facility at the Rutherford Appleton Laboratory (UK) is home to optical tweezers, femtosecond pump-probe spectroscopy, time-resolved stimulated and resonance Raman spectroscopy, time-resolved linear and non-linear infrared transient spectroscopy, to name just a few techniques [36].

Time-resolved spectroscopy has become an important field from x-rays to the far-IR. Both IR and Raman spectroscopies have been adapted to time-resolved studies. There have been a large number of studies using time-resolved Raman [39], time-resolved resonance Raman [7] and higher order two-dimensional Raman spectroscopy (which can provide coupling infonuation analogous to two-dimensional NMR studies) [40]. Time-resolved IR has probed neutrals and ions in solution [41, 42], gas phase kmetics [42] and vibrational dynamics of molecules chemisorbed and physisorbed to surfaces [44]- Since vibrational frequencies are very sensitive to the chemical enviromnent, pump-probe studies with IR probe pulses allow stmctiiral changes to...

Recent advances in time-resolved vibrational spectroscopy (time-resolved infrared [TR-IR] and time-resolved resonance raman spectroscopy) have provided further evidence for the description of aryl nitrenium ions as imino-cyclohexadienyl cations. The C-N stretching frequency in singlet diphenylni-trenium ion (generated by LFP of a N-diphenylaminopyridinium salt in acetonitrile) was measured by time-resolved infrared spectroscopy to be v = 1392 cm , which is significantly higher than the v = 1320 cm of diphenylamine. In the UVA is, the diphenylnitrenium ion shows = 425 and 660 nm, with a lifetime X = 1.5 Rs. ... [Pg.871]
