Diagnostic region

This is probably the most useful diagnostic region as it includes the... 

The X-ray method is not just useful from the qualitative perspective. In samples that contain both anhydrous and hydrate forms, diagnostic regions of the pattern can be identified, and the relative areas of peaks in these regions may be used to establish the relative amounts of each phase. ...

Table 15-2 is a summary of useful signals in the diagnostic region of an IR spectrum as well as some useful signals in the fingerprint region. 

When analyzing an IR spectrum, the first step is to draw a line at 1500 cm. Focus on any signals to the left of this line (the diagnostic region). In doing so, it will be extremely helpful if you can identify the following regions ... 

Remember that each signal appearing in the diagnostic region wiU have three characteristics (wavenumber, intensity, and shape). Make sure to analyTe all three characteristics. 

Draw a line at 1500 cm", and focus on the diagnostic region (to the left of the line). Start by looking at the double-bond region and the triple-bond region. 

The diagnostic region provides the information necessary to solve this problem. Specifically, the compound must have the following bonds ... 

The diagnostic region contains all signals that arise from double bonds, triple bonds, and X—H bonds. 

Identify the signals you would expect in the diagnostic region of the IR spectrum for each of the following compounds. 

IR spectra can be divided into two main regions, called the diagnostic region and the fingerprint region ... 

The diagnostic region provides the information necessary to solve this problem. Specifically, the compound must have the following bonds C=C, C=0, and vinylic C—H. Among the possible choices, there are only two compounds that have these features ...
