The potential of ion mobility (IM) spectrometry in combination with mass spectrometry (MS) for real-time reaction monitoring is reported. The combined IM-MS approach using electrospray ionization affords gas-phase analyte characterization based on both mass-to-charge (m/z) ratio and gas-phase ion mobility

By using steady state and time-resolved (laser flash photolysis and single photon counting) spectroscopic techniques the quenching of the lowest excited singlet (S1) state of 9-cyanoanthracene (9CNA) by the donors (quenchers) 2-methylindole (2MI) and 2-methylindoline (2MIN) in solvents of different

Electrochemical measurements by cyclic voltammetry predict the possibility of occurrence of photoinduced electron-transfer (PET) reactions between the ground state of 2-phenylindole (2PI) (electron donor) and the excited singlet of 9-cyanoanthracene (9CNA) molecule acting as an electron acceptor. However, 2PI should

Tryptophanase was generally considered to be inactive towards tryptophan derivatives substituted at 2-position of the indole ring. We have shown that cells containing tryptophanase catalyze the formation of 2-methyl-L-tryptophan from 2-methylindole and L-serine, and from 2-methylindole, pyruvate and ammonium ion.

The adsorption of indole and its 2-methyl derivative from aqueous solutions onto cobalt(II)-carboxylated diaminoethane sporopollenin (CDAE-sporopollenin) was studied using a fixed-bed column at 25+/-0.1 degrees C. Minicolumn adsorption studies showed that the breakthrough and the total adsorption capacities of CDAE-sporopollenin
