Spectral line shape or spectral line profile describes the form of an electromagnetic spectrum in the vicinity of a spectral line – a region of stronger or weaker intensity in the spectrum. Ideal …

Lecture 6: Spectral Lineshapes A typical lineshape function 1. Background introduction 2. Types of line broadening 3. Voigt profiles 4. Uses of quantitative lineshape measurements 5. Working …

In describing the shape or profile of a spectral line, we introduce the notion of the atomic line absorption coefficient. This is a probability density function that describes the probability that a …

A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum. It may result from emission or absorption of light in a narrow frequency range, compared with …

Oct 3, 2016 · Spectral Line Shapes, Widths, and Shifts. Observed spectral lines are always broadened, partly due to the finite resolution of the spectrometer and partly due to intrinsic …

Abstract. Spectral line-shape models are an important part of understanding high-energy-density (HED) plasmas. Models are needed for calculating opacity of materials and can serve as …

Feb 18, 2025 · What element, and what transition, creates this line? What is the equivalent width of the strong line?

There are a number of standard spectral lines which are frequently used as wavelength references, e.g. for the characterization of optical glasses. Spectral lines always exhibit a finite …

The line shape reflects the sum of contributions of single particles with their distict velocity vectors. In a real sample, particles clash with each other which, in turn, disturbs their energy. …
