2-columns File Format

The 2-column file format used in Spview is designed to store positional and intensity data of lines. This is the simpliest way to represent a spectrum where each row in the file corresponds to a line. The first column contains the position of the line, generally in \(\text{cm}^{-1}\), and the second column stores the corresponding intensity value. The two colums are separated by a coma or a space.

Here’s an example of such a file:
