Study of Vibrational Dynamics in Alkali-Alkalide Systems.
We aim to investigate the vibrational dynamics of frozen solutions of alkalides (K+ Na-) comprising the fully methylated aza-crown hexamethyl hexacyclen (HMHC). This proposal... -
PTM dependant polymorphism of acrylamide
Our recent X-ray and single crystal studies have shown that acrylamide can undergo different phase transformations depending on the pressure transmitting medium used i.e.... -
The Pressure and Temperature Dependence of the Structure of Ammonium Triiodide
We have shown that the molecular ionic solids MI3 (M=Tl, Cs, Tl, NH4) undergo structural phase transitions below 3.4 GPa at RT to give the same new high pressure phase (HP) with... -
A high-pressure study of N,N'-dimethylurea
This proposal seeks to explore the high-pressure structural behaviour of N,N¿-dimethylurea. Two new high-pressure forms have been structurally characterised using x-ray methods,... -
Pressure-Induced Linkage Isomerism in a Prussian Blue Analogue
The Prussian blue analogue K0.4Fe4[Cr(CN)6]2.8.16H2O (1) is a soft ferromagnet at ambient pressure with a critical temperature (Tc) of 19 K. Bridging cyanides are oriented in... -
Copy of: The Effect of Pressure on the Crystal Structure Titanium Tetrachloride
At ambient pressure and temperature TiCl4 is a fuming yellow liquid. On cooling it forma a solid composed of essentially isolated tetrahedral molecules; the same structure is...
