  • There have been various comprehensive and stand-alone text books on the introduction to Molecular Photochemistry available in market. A few fantastic books to mention are: ‘Modern Molecular Photochemistry of Organic Molecules’ by N. J. Turro et. al. and ‘Fundamentals of Photochemistry’ by K. K. Rohatgi- Mukherjee. These books along with others give crystal clear idea on the common topics both in pictorial and intuitive terms.

  • Absorption of light (W or visible) by the ground state of a molecule (So) generates electronically excited states, either directly (the singlet states) or after intersystem crossing from the singlet manifold (the triplet states). Alternatively, triplet states may be generated by energy transfer from another excited state (a sensitiser). In both multiplicities, very fast internal conversion leads to the lowest states (S1 and TI respectively). These states, although still quite short lived (typical lifetime 610-8 s for S1 and ...

  • Thea-phycoerythrocyanin subunits of the different phy-coerythrocyanin complexes of the phycobilisomes from the cyanobacterium Mastigocladus laminosusperform a remarkable photochemistry. Similar to phytochromes – the photoreceptors of higher plants – the spectral pro-perties of the molecule reversibly change according to the irradiation wavelength. To enable extensive analyses,the protein has been produced at high yield by improving purification protocols.
