IR spectrum of DCI 100 80 60 40- 2260 2160 2060 1960 1860 Wovenumbers (cm-1) IR

Question

IR spectrum of DCI 100 80 60 40- 2260 2160 2060 1960 1860 Wovenumbers (cm-1) IR spectrum of DCI Prelab questions 1. Using the data in the above spectrum for DCI, complete the analysis described in these instructions and in the textbook for DCI. Find values for B, I, r, etc. You can then use these results to compare to HCI in the lab. Why is it necessary to record reference spectra? What is the advantage of recording a spectrum with 16 scans? Why is it preferable to scan 16 times with a short time step rather than once with a longer acquisition time at each data point? 2. 3.

Explanation / Answer

2. It is necessory to record reference spectra because reference measurement make possible to eliminate instrument influence.

3. Advantage giving 16 scans in IR because it reduces noise in the instrument.
