On a generalization of the generating function for Gegenbauer polynomials

January 28, 2013
Author(s)
Howard S. Cohl
We derive a Gegenbauer polynomial expansion for complex powers of the distance between two points in $d$-dimensional Euclidean space. The argument of the Gegenbauer polynomial in the expansion is given by the cosine of the separation angle between the two

Alternative Analyses of Measurements of the Planck Constant

July 5, 2012
Author(s)
Blaza Toman
We compare different methods for the adjustment of the Planck constant using recent, inconsistent data. First we discuss the popular Birge ratio method. By stating the underlying statistical model we critically assess and modify this method. We then

Thermodynamic Properties of Air from 60 to 2000 K at Pressures up to 2000 Mpa

October 1, 1999

M D. Panasiti, Eric Lemmon, S G. Penoncello, R. T. Jacobsen, Daniel G. Friend
A thermodynamic property formulation for standard dry air based upon experimental P-p-T, heat capactiy, and speed of sound data and predicted values, which extends the range of prior formulations to higher pressures and temperatures, is presented.

The Infrared Spectra of the NH 3 -d n + Cations Trapped in Solid Neon

… in earlier gas-phase studies for the three infrared-active fundamentals of 14 NH 3 + . The corresponding fundamentals of 15 NH 3 + , 14 ND 3 + , and 15 ND 3 + have been observed as have been many of the fundamentals of the partially deuterium-substituted cations, …

The Infrared Spectrum of HOOH+ Trapped in Solid Neon

Warren E. Thompson, Catherine L. Lugez, Marilyn E. Jacox
… appear which can be assigned to the three infrared-active fundamentals of trans-HOOH+. When the Ne:H2O2 deposition … include new peaks which can be attributed to vibrational fundamentals of trans-HOOD+ and trans-DOOD+. Density functional calculations of the vibrational fundamentals of the three hydrogen peroxide cation …
