Vibrationally resolved photoelectron spectrum of ZnBr−
Journal of Molecular Spectroscopy, 2019Abstract Determination of the vibrational frequency of the ZnBr radical has been elusive, having previously been reported as 220 cm−1 and 318 cm−1 by different investigators. Recently, Burton and Ziurys reported a rotational spectrum of ZnBr from which they were able to estimate a harmonic frequency of 284 cm−1 and an anharmonicity of 1.0 cm−1.

The spectrum of ?-resolvable designs with block size four
Journal of Combinatorial Designs, 2001A design is called \(\alpha\)-resolvable if its blocks can be partitioned into disjoint classes such that each point is on exactly \(\alpha\) blocks of any given class. The authors prove that the necessary arithmetic conditions for the existence of an \(\alpha\)-resolvable design with block size 4 are also sufficient, with the single exception of ...

This chapter introduces the notion of the spectrum of an operator (possibly unbounded) on a Hilbert space. The theory of the resolvent operator is developed and used to establish basic properties of the spectrum.

Journal of Fluid Mechanics, 2019
A two-dimensional analysis of the resolvent spectrum of a Mach 1.6 transitional boundary layer impacted by an oblique shock wave is carried out. The investigation is based on a two-dimensional mean flow obtained by a RANS model that includes a transition

The eigenvalues of an n × n matrix M constitute a (finite) point set in the complex plane, called the spectrum of M. If A is any linear operator in a Hilbert space ℌ, the complex plane ℂ is similarly decomposed into two parts: the spectrum of A, denoted by σ(A), and the resolvent set, denoted by ρ(A).

The Resolvent and The Spectrum
2009A large, and the most important, part of operator theory is the study of the spectrum of an operator. In finite dimensions, this is the set of eigenvalues of A. In infinite dimensions there are complications that arise from the fact that an operator could fail to be invertible in different ways.

Time-resolved electron spectrum measurements on the FELIX facility
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1993Measurements of the FELIX electron energy spectrum using multichannel secondary emission monitors are described. The detectors have a time resolution of 50 ns and span typically 4% in electron energy over 32 channels. Aspects of the design of the OTR detector and energy spectrometer for FELIX are presented, along with data recently acquired with the ...

Vibrationally Resolved LIF Spectrum of Tertiary Methylcyclohexoxy Radical
The Journal of Physical Chemistry A, 2012Cyclohexoxy radical and its substitutes are intermediates of the combustion reaction in automobile engines, and hence play an important role in the atmospheric chemistry. Spectroscopic and conformational studies can provide convenient methods to monitor these species.

Spectrum Resolved SNR Monitoring of In-Service Channel
Optical Fiber Communication Conference (OFC) 2024We propose and experimentally demonstrate a novel scheme to monitor the spectrum resolved SNR with receiver ADC buffer data. SNR accuracy of 0.2dB can be achieved, and filtering impact can be separated from link noise.
