  • 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 ...

  • Photosynthesis of micro algae is often inhibited by salt stress (Kirst, 1990). Such an inhibition may be explained by a decrease in PSII activity. Indeed, in the green microalgae, salt stress inhibits PSII activity in Dunaliella tertiolecta and Chlamydomonas reinhardtii that is associated with a state-2 transition (Gilmour et al., 1985, Endo et al., 1995). In the cyanobacteria, it has been suggested that the decreased PSII activity in salt-stressed cells is associated with the state-2 transition (Schubert et al., 1993; Schubert and Hagemann, 1990).

  • Few of us can any longer keep up with the flood of scientific literature, even in specialized subfields. Any attempt to do more and be broadly educated with respect to a large domain of science has the appearance of tilting at windmills. Yet the synthesis of ideas drawn from different subjects into new, powerful, general concepts is as valuable as ever, and the desire to remain educated persists in all scientists.

  • The decreased maximum quantum yield of primary photochemistry (Fv/Fm), interpreted as photodamage (Powles, 1984; Torzillo et al., 1998; Maxwell & Johnson 2000), may be due to an inactivation of PSII reaction centers, an inhibition of electron transport at both donor and acceptor sides of PSII, and a distribution of excitation energy transfer in favor of PSI (Lu & Vonshak, 1999; Lu et al., 1999; Lu & Vonshak, 2002), increasing the cyclic electron flow around PSI (Gilmour et al., 1982; Joset et al., 1996).

  • Vitamin D Photochemistry Cutaneous exposure to UV-B causes photolysis of epidermal 7dehydrocholesterol converting it to pre-vitamin D3, which then undergoes a temperature-dependent isomerization to form the stable hormone vitamin D3. This compound then diffuses to the dermal vasculature and circulates systemically where it is converted to the functional hormone 1,25-dihydroxyvitamin D3[1,25(OH)2D3]. Vitamin D metabolites from the circulation or those produced in the skin itself can augment epidermal differentiation signaling.

  • 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.
