The sol–gel synthesis of glasses and ceramics has received a great amount of scientific and technological interest. The close control of the evolution between the sol and gel states allows the elaboration of highly appropriate materials for technic

International audience; The study of the sol to gel transition of silicon based materials obtained from alkoxide precursor Si(OCH3)4, catalyzed by a nucleophilic activator (DiMethylAminoPyridin, DMAP) in methanol has been performed by rheological mea

Publikováno v: SPIE Proceedings.

We present terminal population of seven vibrational levels, v"=1-8, in Na2 supersonic beam formed by pure Sodium expansion. It was determined by the laser induced fluorescence method for source pressure x nozzle diameter product p0d=0.32, and covers

Anomalous behaviour of the Landé factors and the chemical shift close to the dissociation limit of the B state of molecular iodine

Autor: G. Gouedard, Jacques Vigué, J.C. Lehmann, Michel Broyer

Publikováno v: Chemical Physics Letters. 43:118-121

Resonances in a modulated light beam have been observed on five transitions in the visible band system of I 2 . Lande factors g J and chemical shifts g 1 have been measured for levels very close to the dissociation limit of the B state.

Lif study of the I2+F → IF+I reaction: population of the v' = 0 level of IF

Autor: B. Girard, G. Gouedard, Jacques Vigué, N. Billy

Publikováno v: Chemical Physics Letters. 136:101-105

We have attempted to detect the v' =0 level in IF molecules produced by the reactive collision I2+F → IF+I under crossed-beam conditions. The signal that we have observed is shown to be due to a background IF vapour. This is an important result as
