| Why don't I get
any matches when I perform a Text search? Although the FTIRsearch.com database
contains nearly 87,000 spectra of various compounds, it does not contain every known
compound or material. However, it is possible that the spectrum is in the database, but
your search criteria were too specific to find a match. Here are some hints to help
optimize your search when an initial search fails.
| 1. |
All of the spectral collections in the
database have come from different sources and labs, so not all the spectra have the same
level of detail. For example, many spectra in some of the smaller collections do not have
CAS numbers or molecular formulas assigned to them. All spectra have at least one primary
compound name and most have secondary and trade names. Try searching by only filling in
the compound name and leaving the other fields blank. |
|
|
| 2. |
Do not fill in the CAS number field when
searching Compound Name or Formula. |
Use root words in the Compound Name rather than the
full chemical name to avoid punctuation and spacing mismatches (i.e.,
"hydrofuran" rather than "tetra-hydrofuran"). |
|
| How can I find out
if the database contains a spectrum I want? If you are already a registered
FTIRsearch.com member, the best way to find out is to simply go in and try a Text search.
As long as you have credits in your account you can run as many text searches as you like
for free (you are only charged when you view the spectra).
If you are not a registered member but are interested in learning more about the
spectra in the FTIRsearch.com database, you can view the list of compounds and spectra in
each sub-collection by downloading the Adobe PDF files from the
Library descriptions. |
