The following 1h nmr absorptions were obtained on a spectrometer operating at 200 mhz and are given in hz downfield from tms. Convert the absorptions to δ units.

Explanation:

We will use the formula below:

Chemical shift in ppm =peak position in Hz (relative to TMS) /

spectrometer frequency in MHz.

a) 956Hz/200Hz= 4.78 ppm

b) (2.40E3)/200Hz= 12 ppm

c) (1.97E3)/200Hz = 9.85 ppm

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
