The electronic structure and photoinduced electron transfer processes in a K+ fluorescent sensor that comprises a 4 amino naphthalimide derived fluorophore with a triazacryptand lig and is investigated using density functional theory (DFT) and time dependent density functional theory (TDDFT) in order to rationalise the function of the sensor. The absorption and emission energies of the intense electronic excitation localised on the fluorophore are accurately described using a SCF Kohn Sham DFT approach, which gives excitation energies closer to experiment than TDDFT. Analysis of the molecular orbital diagram arising from DFT calculations for the isolated molecule or with implicit solvent cannot account for the function of the sensor and it is necessary to consider the relative energies of the electronic states formed from the local excitation on the fluorophore and the lowest fluorophore’chelator charge transfer state.
The passing last week of the nakedly communal Citizenship (Amendment) Bill will further encourage the world to see us as a nation driven by religious bigotry and sectarian prejudice. The rehyphenation of India with Pakistan will now proceed even more rapidly. This may be welcomed and cheered on by anchors at Republic and Zee News.
So, Can antiques or an inanimate object really be possessed, haunted? Do you love antiques, is your home brimming with them? Do you spend hours in search of wonderful treasures to add to your dcor? When you find a treasure do you purchase it without little thought to where your treasure lived, and who owned it before you? Have you ever pondered what attracts you to certain antiques? When you spot something you just know you must have, does your sixth sense just kick in, and you just purchase it? Have you ever purchased an antique that once it’s in your home you noticed odd occurrences happening? Such as, unexplained bumps in the night, quite ghostly murmurs in the still of the afternoon or perhaps even things being moved or go missing? You just may have brought home a haunted antique. It seems hard to believe that an inanimate object could carry some residual energy from its previous dead owner. Whereas the previous owner has in some way attached itself to that object and has the power to project itself in the form of a “haunting”.
Unfortunately, almost four years passed before I had another chance to speak with Harrison and address some of these issues. What is here are highlights from our two conversations, one from that visit in August of 1995, the other a phone conversation held September 6, 1999. I hope that a sense of how Harrison locates and identifies himself in the world, both geopolitically and musically, will emerge through the selections of these conversations offered here..
