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

1. The thiobarbituric acid (TBA) reaction, widely applied to the detection of autoxidation in polyunsaturated fatty acids, can be used to measure free-radical damage to amino acids, carbohydrates and nucleic acids. 2. In all of these systems malondialdehyde (MDA) is

The indole moeity is present in many substances of biological occurrence. Its metabolism, in most cases, involves an oxidative pathway. This study reports the oxidation of a series of indole derivatives, including several of biological origin, catalyzed by horseradish peroxidase
