Determination and Use of Secondary Infrared Intensity Standards

Autor: John E. Bertie, Shuliang L. Zhang, Yoram Apelblat, C. Dale Keefe, R. Norman Jones

Publikováno v: Applied Spectroscopy. 49:1821-1825

The presentation of absorption intensities in infrared spectra is usually limited to relative intensities instead of absolute intensities. The measurement of absolute intensities can be facilitated by the use of secondary intensity standards. Such st

Infrared Intensities of Liquids XVIII: Accurate Optical Constants and Molar Absorption Coefficients between 6500 and 800 cm−1 of Dichloromethane at 25°C, from Spectra Recorded in Several Laboratories

Autor: John E. Bertie, Zhida Lan, R. Norman Jones, Yoram Apelblat

Publikováno v: Applied Spectroscopy. 49:840-851

This paper presents the results of a study to obtain accurate infrared absorption intensities of liquid benzene at 25°C. To achieve this we have determined the agreement between the intensities measured by different spectroscopists using the same in

Infrared Intensities of Liquids XIII: Accurate Optical Constants and Molar Absorption Coefficients between 6500 and 435 cm−1 of Toluene at 25°C, from Spectra Recorded in Several Laboratories

Autor: John E. Bertie, Yoram Apelblat, R. Norman Jones, C. Dale Keefe

Publikováno v: Applied Spectroscopy. 48:127-143

This paper presents accurate infrared absorption intensities of liquid toluene at 25°C. The accuracy is estimated from the agreement between the intensities measured by different spectroscopists using the same instrument in the same laboratory and a

Compact Table for the Publication of Infrared Spectra That are Quantitative on Both Intensity and Wavenumber Axes

Autor: R. Norman Jones, John E. Bertie, Yoram Apelblat

Publikováno v: Applied Spectroscopy. 47:1989-2001

A Compact Table format is presented for the publication of infrared spectra that are quantitative on both intensity and wavenumber axes. The format is illustrated with a molar absorption coefficient spectrum, Em(ν˜) vs. ν˜, and with infrared real

Ultra-violet absorption spectrum of anhydrous nitric acid

Autor: R. NORMAN JONES, G. D. THORN, M. LYNE, E. G. TAYLOR

Publikováno v: Nature. 159(4031)

RECENTLY, Ingold and co-workers have presented evidence of the existence of the nitronium ion (NO2+) in solutions of nitric acid in concentrated sulphuric acid1,2. We wish to report some observations on the ultra-violet absorption spectrum and electr

Computer programs for absorption spectrophotometry

Autor: R. Norman Jones

Publikováno v: Applied optics. 8(3)

Brief descriptions are given of twenty two modular computer programs for performing the basic numerical computations of absorption spectrophotometry. The programs, written in Fortran IV for card input and output, are available from the National Resea

Infrared intensities of liquids VIII. Accurate baseline correction of transmission spectra of liquids for computation of absolute intensities, and the 1036 cm−1 band of benzene as a potential intensity standard

Autor: John E. Bertie, C. Dale Keefe, R. Norman Jones

Publikováno v: Canadian Journal of Chemistry. 69:1609-1618

FT-IR transmission spectra of liquids in well-made and firmly held cells with KBr or NaCl windows are usually very reproducible except that their baselines often show unexpected variations. To obtain absolute absorption intensities from these spectra

Infrared intensities of liquids. part VII : progress towards calibration standards

Autor: Douglas J. Moffatt, C. Dale Keefe, R. Norman Jones, Henry H. Mantsch, John E. Bertie

In 1961 the International Union of Pure and Applied Chemistry (IUPAC) formulated calibration standards for wavenumber measurements in the infrared, but comparable standards for infrared intensity measurements are still not available. In 1985 IUPAC es
