The 5 5 13Cand 4 I5Nnmr transitions in chlorophyll a and its magnesium-free derivative pheophytin a have been assigned. Emphasis is placed on the quaternary carbon atoms of the macrocycle which carry ...
The Quantum Theory of General Relativity at Low Energies
Quantum field theory low energy quantum the interaction energy general relativity low energy
2014/12/23
In quantum field theory there is now a well developed technique, effective field theory, which allows one to obtain low energy quantum predictions in “non-renormalizable” theories, using only the degr...
