Picosecond linear dichroism and absorption anisotropy of hypcorellin: toward a unified picture of the photophysics of hypericin and hyporcrellin
Article Abstract:
A study was conducted to analyze the photophysics of hypocreelin using transient absorption spectroscopy. Amplified dye laser pulses were utilized to carry out the time-resolved linear dichroism experiments. In addition, the isotropic transient absorption trace was directly determined. Experimental results indicated a hypercin-like transient in hypocrellin that correlates with the link between the photophysics of hypericin and hypocrellin.

Local amide I mode frequencies and coupling constants in polypeptides
Article Abstract:
The site dependencies of the local amide I mode frequencies and vibrational coupling constants between neighboring peptides, were investigated by performing beta-sheet polypeptide conformations with two to five peptide bonds. It was found that the 1-2 coupling constants were strongly dependent 3-D confirmation.
