Description
I found 2 or 3 mentions of this format in my inbox, from the first 10 years of xylib development.
Looking for more details I found:
In Wikipedia:
The SPC file format is a file format for storing spectroscopic data.
The SPC file format is a file format in which all kinds of spectroscopic data,
including amongst others infrared spectra, Raman spectra and UV/VIS spectra.
The format can be regarded as a database with records of variable length
and each record stores a different kind of data (instrumental information,
information on one spectrum of a dataset, the spectrum itself or extra logs).
It was invented by Galactic Industries as generic file format for its programs.
Their original specification was implemented in 1986,
but a more versatile format was created in 1996.Galactic Industries was purchased by Thermo Fisher Scientific
who now maintain and develop the GRAMS Software Suite
On a randomly googled web page:
More about working with Galactic GRAMS *.spc files:
Before Galactic dissolved into THERMO corporation, there used to be around some information for software developers for working with the binary spc file type. At the moment, none of them is available.
