Because of mass assignment onto grid points in the measurement of the power spectrum using the Fast Fourier Transform (FFT), the raw power spectrum |δ f (k)| 2 estimated with FFT is not the same as the true power spectrum P (k). In this paper, we derive the formula which relates |δ

Studying the energy level structure of di€erent molecules by means of spectroscopy is one of the ®elds in physics and chemistry. In this paper, we describe a knowledge-based system, molecular spectroscopic assignment assistant (MOSAA), which can assist researchers in the assignment of the far-infrared and infrared absorption peaks of the molecules in question by using the spectral information p...

The 70.6 MHz llB NMR spectrum of (3)-1,2-B&H, consists of five doublets of relative intensities 2/3/2/1/l reading upfield. The proposed assignment of these doublet resonances is B (4, 7); B (6) and B (9, 12); B (5, 11); B (8) and B (10) respectively. The l ‘B NMR spectrum of [(3)-1,2-B&H, JZCocontains five doublets of relative intensities 1/1/4/2/l reading upheld The proposed assignment of thes...

The evidence bearing on our revision of the early assignment of the circular dichroism spectrum of the maximally unordered polypeptide chain is reviewed. Our initial, as well as subsequent, studies are believed to support the proposed revision in assignment. This conclusion need not be modified in the light of recent work on water-soluble, non-ionizable polymers.

The compressed sensing NMR (CS-NMR) is an approach to processing of nonuniformly sampled NMR data. Its idea is to introduce minimal l(p) -norm (0 < p ≤ 1) constraint to a penalty function used in a reconstruction algorithm. Here, we demonstrate that 2D CS-NMR spectra allow the full spectral assignment of near-symmetric β-cyclodextrin derivatives (mono-modified at the C6 position). The applicati...

Recently, there is an urge to allocate chunks of the spectrum to the wireless service providers on a more dynamic basis rather than the current practice of static allocation. This shift in paradigm is a result of many studies that indicate the improper utilization of the spectrum by the service providers due to the static spectrum assignment. Also, the use of the spectrum has been found to be s...

Resonance assignment is the first stage towards solving the structure of a protein. This is normally achieved by the employment of separate inter and intra residue experiments. By utilising the mixed rotation and rotary recoupling (MIRROR) condition it is possible to double the information content through the efficient bidirectional transfer of magnetization from the CO to its adjacent Cα and t...

The tremendous growth of wireless networks requires an efficient use of the scarce radio spectrum allocated to wireless communications. However, the main difficulty against an efficient use of radio spectrum is given by interferences, caused by unconstrained simultaneous transmissions, which result in damaged communications that need to be retransmitted leading to a higher cost of the service. ...

The Huggins band of ozone is investigated by means of dynamics calculations using a new (diabatic) potential energy surface for the 3 (1)A'(1B2) state. The good overall agreement of the calculated spectrum of vibrational energies and intensities with the experimental spectrum, especially at low to intermediate excitation energies, is considered as evidence that the Huggins band is due to the tw...
