The Molecular Spectroscopy Group and East Anglia Region of the RSC will jointly host the 3rd Terahertz Spectroscopy meeting to be held on Thursday 31st October 2013:
Recent Advances in Spectroscopy at Terahertz Frequencies
This 3rd one day meeting will be held at Thomas Graham House in Cambridge and will focus on recent advances in terahertz spectroscopy.
Terahertz radiation, the part of the electromagnetic spectrum between microwaves and infrared radiation, has unique properties in that it easily penetrates through most polymeric materials and is therefore an exciting new tool to study such materials. As well as being a non-destructive imaging probe, in organic molecular crystals terahertz radiation interacts with vibrational modes that extend across large domains of a crystal lattice. This makes terahertz spectroscopy unique: even though it is possible to excite molecules using a variety of energies it is only through the careful selection of the low energy in the terahertz range that it is possible to selectively excite crystal lattice vibrations and study the presence and nature of interactions between molecules.
