Mid-infrared study of deoxyadenosine at high pressures: evidence of phase transitions.


Room temperature mid-infrared experiments between 500 and 1800 cm(-1) have been performed on crystalline deoxyadenosine as a function of pressure up to about 10 GPa. Discontinuities observed near 2 and 4 GPa indicate that two separate phase transitions occur at these pressures. Changes in the spectra suggest that both transitions involve a rearrangement of… (More)
