In the structure of the title compound, C(14)H(12)ClNO, the N-H and C=O bonds are trans to each other. Furthermore, the C=O bond is syn to the ortho-methyl group in the benzoyl ring, similar to what is observed in 2-methyl-N-(4-methyl-phen-yl)benzamide and 2-methyl-N-phenyl-benzamide. The amide linkage (-NHCO-) makes dihedral angles of 36.9 (7) and 46.4 (5)° with the aniline and benzoyl rings, ...
A pump-probe spectroscopic study of photoinduced forward electron transfer and geminate recombination between donors and acceptors located in the head group regions of micelles is presented. The hole donor is octadecyl-rhodamine B (ODRB) and the hole acceptor is N,N-dimethyl-aniline (DMA). The experiments are conducted as a function of the DMA concentration in the dodecyltrimethylammonium bromi...
