Introduction
Overview
SpecLine is a high-end tool for all scientists and engineers working in the field of spectroscopy, such as
astrophysics, plasma science or plasma processing. This tool makes it easy for you to do the following:
 Evaluate spectral data (i.e., find specific lines in spectra).
 Identify unknown peaks as well as atomic lines and molecular bands in spectral data. Peaks of
lines and bands can be found almost instantly by scanning the extensive database for atoms and
molecules and using several powerful filter functions. Much information about the lines in the
evaluated spectrum is only a few mouse clicks away.
 Compare data from different measurements. All customary spectroscopic file formats can be
processed directly, which allows an easy comparison of spectral data even from different data
acquisition systems. Every single spectrum may be evaluated and adjusted on its own.
An extensive and detailed help file is available to supports you while you work with SpecLine.
Finding Peaks in Spectra
SpecLine makes it easy to find peaks. A powerful search algorithm searches for peaks of lines and bands
in spectral data. Even difficult structures, i.e. double lines, line shoulders and complex band structures,
are found easily and marked for further evaluation. For noisy data, several filter functions for data
smoothing are available. You can find peaks with automatically generated parameters or with user-
defined parameters for data smoothing or noise limits.
Identifying Atomic Lines and Molecular Bands
SpecLine saves you from the time-consuming job of scanning books and articles for atomic or ion lines
and molecular bands that match the line or band in your spectra. To do this, SpecLine uses an extensive
and up-to-date database. Almost instantly, all important information is available for a specific line without
you opening a book. You can select specific elements for the identification process to avoid unnecessary
hits and to shorten database-scanning time.
