Theoretical study of the absorption spectra of the lithium dimer
نویسندگان
چکیده
For the lithium dimer we calculate cross sections for absorption of radiation from the vibrational-rotational levels of the ground X Σg electronic state to the vibrational levels and continua of the excited A Σu and B Πu electronic states. Theoretical and experimental data are used to characterize the molecular properties taking advantage of knowledge recently obtained from photoassociation spectroscopy and ultra-cold atom collision studies. The quantum-mechanical calculations are carried out for temperatures in the range from 1000 to 2000 K and are compared with previous calculations and measurements. PACS numbers: 33.20.-t, 34.20.Mq, 52.25.Rv Typeset using REVTEX

متن کاملThermodynamic Characterization of the Aggregation Phenomena of SafranineT by Spectral Titration and Chemometric Analysis
The dimerization constants of Safranine T have been determined by studying the dependence of its absorption spectra on the temperature in the range 30–70 ◦C at different total concentrations of Safranine T (1.03×10−5, 1.44×10−5 and 1.73×10−5 M). The monomer–dimer equilibrium of Safranine T has been determined by applying MCR-ALS method on the absorpti...
