The ones who get accepted are the cream of the industry.
And one shall for sure benefit by ordering his papers from the best scribes.
With the help of quantum mechanical calculations (Schroedinger equation) you can find the frequencies of basic stretching and bending modes: Based on the equation, one would always expect a sharp lines at a well defined wavenumber.
Unfortunately, the change in vibration modes is always accompanied with change in rotational mode (Stokes and Anti-Stokes).
Not the least important thing in provision of the dissertation services is the experience of our employees in this field.

The following sequence is observed: Ring strain usually increases the C=O stretching frequency.
Conjugation of teh carbonyl group with other double bonds (aromatics, alkenes) or the formation of hydrogen bonds decreases the bond strength (shift: 15-60 cm).
An interpretation of an IR spectrum should include a detailed assignment of the peaks: exact wavenumber from the spectrum (integer), the intensity (w/m/s/br) and which functional group it represents, and maybe in addition the corresponding literature value.
However, it is not necessary to interpret every little peak in the IR spectrum.
