Lifetimes of the lowest triplet state of ozone by intracavity laser absorption spectroscopy

Characterization of Triplet States in Doubly Charged Positive Ions : Assignment of the ' ng - ' Z , + Electronic Transition in N ; + Diane

The first direct spectroscopic evidence and characterization of triplet states in a molecular dication is reported. The 'II, ,ZU+ electronic absorption between excited states of N22+ is recorded by ion-laser coaxial beam photofragmentation spectroscopy. Over 300 rotational lines are resolved, and 13 parameters characterizing the upper and lower electronic states are determined. The results are ...

Heteroleptic cationic iridium(III) complexes bearing naphthalimidyl substituents: synthesis, photophysics and reverse saturable absorption.

Three heteroleptic cationic iridium(iii) complexes containing a cyclometalating 2-[3-(7-naphthalimidylfluoren-2'-yl)phenyl]pyridine ligand and different diimine (N^N) ligands (N^N = 2,2'-bipyridine (bpy, ), 1,10-phenanthroline (phen, ), and 5,5'-bis[7-(benzothiazol-2'-yl)fluoren-2'-yl]-2,2'-bipyridine (BTF-bpy, )) were synthesized and characterized. The photophysics of these complexes was syste...

Solid state intracavity laser absorption spectroscopy spectro temporal transient behavior of a Ti:Al2O3 laser

High Resolution Ftir Spectroscopy

In FT-ICLAS, the aim is to improve the absorption detection sensitivity. The experiment combines IntraCavity Laser Absorption Spectroscopy (ICLAS) with FTIR spectroscopy. ICLAS is a well known instrumental technique in which a sample is inserted in a cell placed inside a broadband, multimode laser cavity. The laser is operating in pulsed mode and intracavity absorption rises as the laser wave b...

Intracavity absorption spectroscopy with a turbulent detuned actively mode-locked Ti:sapphire laser.

Intracavity laser absorption spectroscopy (ICLAS) is an extremely sensitive method for the detection of very weak absorptions. However, the conventional use of multimode lasers has thus far significantly reduced its ability to detect in situ molecules and its sensitivity. We propose the use of a new type of laser that overcomes these limitations: the turbulent detuned actively mode-locked (TDAM...
