The gas-phase electronic spectrum of cyclic-B3 (D3h) radical has been remeasured in a supersonic molecular beam using a mass-selective resonant 2-color 2-photon technique, leading to a revision of previously reported spectroscopic constants. The spec

Infrared spectra of UV photolysed cyanoacetylene and dicyanoacetylene trapped in argon matrices at 10 K have been performed. From cyanoacetylene photolysed at λ >120 nm, we obtained three different isomers. The formation of HCCNC, HNCCC and the exot

The generation and characterization of transient species is a challenge for experimentalists as these species are short-lived and reactive. Our group has focused on the measurement of the electronic spectra of unstable molecules relevant to astrophys

Anions of titanium dioxide produced by sputtering TiO2/graphite composite rods were trapped in 6 K neon matrices following mass selection. The electronic absorption spectrum of titanium dioxide has been measured subsequently, after exposing the matri

Dicyanoacetylene adsorbed on amorphous ice water at 10 K presents an interaction with the dangling H site and induces a s(4) adsorption site formation due to the restructuring of the ice bulk. Warming up the sample provokes the dicyanoacetylene desor

Photoreactivity of cyanoacetylene with water was successively studied in cryogenic matrixes and in the solid phase at lambda > 120 nm. These studies were performed using FTIR spectroscopy, isotopic experiments and DFT calculations at the B3LYP/6-31G
