dc.descriptionEN ESTE TRABAJO, HEMOS REALIZADO CÁLCULOS DE INTENSIDADES VIBRÓNICAS PARA LAS ABSORCIONES ----------------- EN EL SISTEMA DEL TIPO ELPASOLITA CS2NAERCL6. ESTE SISTEMA ES EXTREMADAMENTE DIFÍCIL DE TRABAJAR TANTO DESDE UN PUNTO DE VISTA TEÓRICO COMO EXPERIMENTAL. EN ESTE TRABAJO SE DEMUESTRA QUE EN UN RANGO DE ENERGÍAS DEL ORDEN DE 400 CM -, ES PROBABLE QUE UNA CANTIDAD MUY SIGNIFICATIVA DE TRANSICIONES OCURRA (ALREDEDOR DE 100; SIENDO 25 DE ELLAS DEL TIPO DIPOLO MAGNÉTICO Y LAS OTRAS 75 DE CARÁCTER VIBRÓNICO). ES EN CONSECUENCIA, UNA TAREA FORMIDABLE, EL IDENTIFICAR Y ASIGNAR TODAS ESTAS TRANSICIONES EN FORMA INEQUÍVOCA. ADICIONALMENTE, LA EVIDENCIA EXPERIMENTAL PARA ESTAS ABSORCIONES SE REFIERE A UN TOTAL DE 25 LÍNEAS EN EL ESPECTRO DE LUMINISCENCIA DE ESTE SISTEMA. EL ESPECTRO ES EN SÍ MISMO MUY DESAFIANTE Y UNA IMPORTANTE SUPERPOSICIÓN DE LÍNEAS ESPECTRALES ES ALTAMENTE PROBABLE DE SER OBSERVADA. UN ANÁLISIS CUIDADOSO DE LAS INTENSIDADES VIBRÓNICAS CALCULADAS Y DE LAS FUERZAS DEL OSCILADOR PARA ESTA VARIEDAD DE EXCITACIONES NOS INDICA QUE EL MODELO DE CÁLCULO UTILIZADO ES FLEXIBLE Y APROPIADO PARA TRABAJAR CON ESTE TIPO DE SISTEMAS. EN UN PRÓXIMO ARTÍCULO, EXAMINAREMOS LA ALTA INTENSIDAD, BASTANTE POCO USUAL, ASOCIADA CON LAS EXCITACIONES-----------------.AbstractIN THIS CURRENT STUDY, WE HAVE UNDERTAKEN VIBRONIC INTENSITY CALCULATIONS FOR THE ABSORPTIONS--------------- IN THE CS2NAERCL6 ELPASOLITE TYPE SYSTEM. THIS SYSTEM IS EXTREMELY COMPLICATED TO HANDLE FROM BOTH A THEORETICAL AND AN EXPERIMENTAL VIEWPOINTS. THIS THEORETICAL WORK SHOWS THAT OVER AN ENERGY RANGE OF ABOUT 400 CM -, A SUBSTANTIAL AMOUNT OF TRANSITIONS ARE LIKELY TO TAKE PLACE (ABOUT 100 TRANSITIONS; TWENTY FIVE OF THEM ARE MAGNETIC DIPOLE ALLOWED AND SEVENTY FIVE ARE VIBRONICALLY ALLOWED). IT IS THEN A FORMIDABLE TASK TO IDENTIFY AND ASSIGN ALL OF THESE TRANSITIONS IN A NON-AMBIGUOUS WAY. ALSO THE EXPERIMENTAL EVIDENCE AVAILABLE FOR THESE ABSORPTIONS IS RELATED TO A TOTAL OF ABOUT TWENTY LINES IN THE LUMINISCENCE SPECTRUM OF THIS SYSTEM. THE SPECTRUM ITSELF IS VERY CHALLENGING AND THE SUPERPOSITION OF SPECTRAL FEATURES IS MOST LIKELY YO OCCUR. A CAREFUL ANALYSIS OF THE CALCULATED VIBRONIC INTENSITIES AND OVERALL OSCILLATOR STRENGTHS FOR THE VARIOUS TRANSITIONS INDICATES THAT THE CURRENT MODEL USED ID BOTH FLEXIBLE AND APPROPIATE TO DEAL WITH THIS KIMD OF SYSTEMS. IN A FORTHCOMING PAPER, WE WILL EXAMINE THA RATHER UNUSUAL HIGH INTENSITY ASSOCIATED WITH THE -------------- EXCITATIONS.es-ES
