This band is intense in the infrared spectra but shows only low intensity in the Raman spectra. If an image is set up with the red ( wavelength) band as band 1 green as band 2, blue as band 3, near infrared as band 4 a natural color display on the computer screen would be set up with the red ( display) channel as band 1. The high- resolution [ formula presented] Fourier transform infrared spectrum of PH 3 is recorded in the region between 3280 and [ formula presented]. A complete vibrational assignment is proposed for the cis conformer Raman depolarization data, several fundamentals are identified for the gauche rotamer based on infrared band contours group.

Having found much ambiguity in the infrared band assignments for polyamide 66 ( PA66), we revisited some of these assignments before using infrared spectroscopy to assess microstructure changes resulting from multiple thermal corporating chemical band- assignment in near infrared spectroscopy regression models Frank Westad, a, b Angela Schmidt b and Martin Kermit aM- analyse, oslo,. bcamo Software aS, oslo, norway In this paper, we present an approach for incorporating chemical band assignment information in regression models between frared spectroscopic characterization of oriented polyamide 66: Band assignment and crystallinity measurement.
