This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint

Size-Strain Line-Broadening Analysis of the Ceria Round-Robin Sample

Davor Balzar, N Audebrand, M R. Daymond, A Fitch, A Hewat, J I. Langford, A Le Bail, D Louer, P Masson, Christopher N. McCowan, N Popa, P W. Stephens, B H. Toby
We report the results of a line-broadening study on a ceria sample prepared for a size-strain round robin. The sample was prepared from a recursor hydrated ceria by heating in a silica crucible at 650 C for 45 hours. Another ceria sample wasprepared to

Standardization of Isotope Ratio Measurements for Doping Control

R M. Verkouteren
Pharmaceutical steroids are known to differ in isotopic composition from those produced naturally in the body. By measuring the 13 C/ 12C ratio of specific steroids deteched in urine, the technique of Gas Chromatography-Combustion-Isotope Ratio Mass

The Geometry of Organophosphonates: Fourier-Transform Microwave Spectroscopy and ab Initio Study of Diethyl Methylphosphonate, Diethyl Ethylphosphonate, and Diisopropyl Methylphosphonate

R S. DaBell, R D. Suenram, R J. Lavrich, J M. Lochner, M W. Ellzy, K B. Sumpter, J O. Jensen, A C. Samuels
The rotational spectra of diethyl methylphosphonate (DEMP), diethyl ethylphosphonate (DEEP), and diisopropyl methylphosphate (DIMP) have been acquired using Fourier-transform microwave spectroscopy. Spectroscopic constants have been determined for five

The Infrared Spectrum of NH 3/ u - d n u/ Trapped in Solid Neon

December 1, 2004
Author(s)
Marilyn E. Jacox, Warren E. Thompson
The infrared spectra of normal and deuterium-enriched Ne:NH 3u = 1600:1 deposits at 4.3 K have been observed, and structure associated with almost all of the vibrational fundamentals has been assigned. Although the most prominent absorptions arise from the
