It has been reported in the literature [40] that the hydroxylamine vibrational spectrum absorbs in the wavelength region covered by our ATR-QCL system, including: the N-OH stretch at 9.7 [micro]m, the N[O.sub.3] combination stretch at 7.4 [micro]m, and the N-H stretch at 3.8-4.1 [micro]m.

The inability of the Stokes shift to accurately account for the variation in luminescence yield led to the examination of the vibrational spectrum in an effort to reconcile both Stokes and the energy gap law as a measure of the luminescence yield for low band gap material and proxyoligomeric structures.
These peaks are characteristic for rutile titanium dioxide (Ti[O.sub.2]) phase, whose vibrational spectrum has 4 vibrational bands centered around 145 [cm.sup.-1] ([B.sub.1g]), 445 [cm.sup.-1] ([E.sub.3]), 610 [cm.sup.-1] (A), and 240 [cm.sup.-1] for second-order scattering effect (SOE) [30, 31].
For the analysis of vibrational spectrum, the density of states function g(v) ~ [I.sub.red](v) is used.
The ground-breaking goal of VIBRA is to combine the most detailed molecular information over the entire vibrational spectrum with the highest acquisition speed.

Experimental data corresponding to the vibrational spectrum is displayed in Table 1.
So, while most undergraduates could give a rather accurate manual prediction of an NMR spectrum of a small molecule, the same task for the vibrational spectrum requires sophisticated computer software.
They are analogous to instrumental methods, like looking at the vibrational spectrum of a molecule or its magentic-resonance spectrum.
