End to a Great Conference Season

Nov 02, 2016
September was a busy month for the members of the TAG group! The group spent a majority of the month travelling around the world to present their work and catch up collaborators. The month was capped off by the annual IRMMW-THz meeting, which was held in Copenhagen this year.

Farewell to Johanna

Nov 02, 2016
Johanna Sauerwein, an undergraduate student from Friedrich Schiller University Jena in Germany, has completed a highly productive three-month visit to the TAG group today. She was a valuable addition to the lab, and was a critical component of the research performed during her time. She effectively immersed herself in all areas of research, both on the imaging and spectroscopic sides. She will be sorely missed!

A new method for prediction of amorphous drug stability

Apr 01, 2014
A new method for measuring of molecular mobility in glassy materials has been developed using terahertz spectroscopy. The absorption level of amorphous drugs at terahertz frequencies below Tg correlates with the stability of the drug as an amorphous solid. The molecular mobility responsible for the glass crystallisation significantly decreases at around a universal value of 0.67 Tg. This explains why the commonly used rules of thumb for glasses to remain stable below 0.8 Tg or Tg – 20 K do not work reliably.

Day meeting on THz spectroscopy in Cambridge 18 March 2016

Feb 09, 2016
Together with Teranet, an EPSRC-funded network of UK Universities and companies active in terahertz science and technology, the Molecular Spectroscopy Group and East Anglia Region of the Analytical Division of the RSC will jointly host the 4th terahertz spectroscopy meeting in Cambridge. Following three successful meetings in 2009, 2011 and 2013 with the RSC, this year's meeting is the first one involving Teranet and to mark the occasion we will return to Gonville & Caius College in Cambridge. The meeting will focus on recent advances in terahertz spectroscopy.

New paper: Evidence for a universal change in hydrogen bonding structure below the glass transition temperature

May 21, 2014
In our latest paper, just published in the Journal of Physical Chemistry Letters, we present data that indicates that the Johari-Goldstein secondary relaxation (which is inter-molecular in nature) is still of significant strength at terahertz frequencies below the glass transition temperature. Intriguingly we found that it disappears at the same relative temperature in all hydrogen bonding samples we studied (0.65 T/Tg).
