| This converter translates data files from the
Bruker OPUS FT-IR data format. This format is rather complex and can be used to store
several different kinds of spectral data for a given sample, all within a single data file
(i.e., intererogram, single beam, absorbance, transmittance, etc.). The converter looks
through the file to decide what data block to read using a list of blocks that are most
desirable. When looking for data, it always looks for 3D data first. If that is not found,
it then looks for an Absorbance spectrum, then a Transmittance spectrum, and so on. The
table below shows the order used to detect the different data blocks. Once an instance of
a data block is found, the converter will stop looking in the list and read the spectral
data from that data block. Obviously, some data items that can appear in a Bruker Opus
file cannot be used for spectral searching. In order to give the best results, it is
recommended that you use the Opus software to save your spectrum to a separate file with
only a single data item. This will guarantee that the converter will only read the data
you want to search. If this is not possible, make sure that you do not submit any
multidimensional data sets (i.e., 2D-IR, GC-IR, etc.) as the converter is programmed to
always look for this type of data first. Multidimensional data cannot be searched in the
databases on this site.
