TY - JOUR AU - AU - Suhm, Martin A. AU - Kollipost, Franz T1 - Femtisecond single-mole infrared spectroscopy of molecular clusters PY - 2013 PB - Royal Soc Chemistry N2 - The sensitivity limitations of Fourier transform infrared (FTIR) spectroscopy for the detection of molecular clusters formed in rarefied gas expansions can be overcome by synchronizing intense gas pulses at a low duty cycle with rapid interferometer scans. This turns the broadband FTIR approach into a universal cluster spectroscopy tool applicable from the far (200 cm(-1)) to the near (8000 cm(-1)) IR. It nicely complements more selective and more restricted laser-based techniques and it provides a gas-phase variant of the matrix-isolation method, the main drawback being substance consumption. A survey over the capabilities, limitations and perspectives of this high-throughput nozzle approach to cluster FTIR spectroscopy is given. DO - doi:10.1039/c3cp51515j ER -
