Dinámica vibracional del CCl4

Authors: Rois Orza, Cristina;

Dinámica vibracional del CCl4

Abstract

Se estudia el espectro vibracional, infrarrojo y raman, en fase gaseosa, del cc14 considerando especialmente el efecto de la resonancia de fermi (v3,v1 + v4) que da lugar a desdoblamientos múltiples, de poliadas que dominan prácticamente todo el espectro infrarrojo. Se han utilizado muestras de cc14 enriquecidas isotopicamente 12c 35c14 y 12c37c14, preparadas durante el trabajo, junto con una comercial de 13cc14 y otras de cc14 usual (ambas con composición isotópica natural de cloro). Se reproducen los espectros registrados (ftir con 0.24 y 0.01 cm-1 de resolución). Además de las transiciones fundamentales, v1,v2,v4 y sus sobretonos, se han estudiado las poliadas resonantes encabezadas por v3,v2+v3,v3+v4, v1+v3, 2v3, 2v3+v4, v1+2v3, 3v3 y, prácticamente, todas sus bandas de diferencia, con v4 (y varias con v2 y v1). Como ejemplo, 2v3 implica tres triadas diferentes (2v3, v1+v3+v4, 2v,+2v4) de simetrías a1, e y f2 y un nivel adicional (v1+v3+v4) f1. Cada una de estas transiciones se acompaña, además de secuencias en v2 y v4 resonantes. Se ha identificado una gran parte de estos niveles resonantes, señalando como reducir el conjunto de datos en términos de parámetros de resonancia y constantes armónicas
