Using infrared spectra Flashcards
1
Q
the fingerprint region is
A
the region of wavenumbers between 1500 and 500 cm-1 which should be ignored when analysing infrared spectra
2
Q
to predict the spectrum of an organic compound using the wavenumbers given to you, you have to
A
- draw the compound you have to predict (what is it? eg aldehyde, alcohol…)
- recognise the bonds present
- use the table of wavenumbers given to identify the peaks which will be present in the graph
3
Q
to deduce the functional groups from a list of wavenumbers, you need to
A
- find the range in which the values given fall
- match this value to the functional group in the data table
4
Q
you can deduce the structure of a compound using wavenumbers by
A
- using the wavenumber values present to identify which functional groups are present
- use the molecular formula given to draw the compound with the appropriate functional groups
5
Q
when looking at infrared spectra, concentrate on the regions
A
4000 to 1500 cm-1
