The 'main menu' screen of CASSA; here the student must choose which spectrum/technique (s)he wishes to solve next.


The student has already measured the integrals, and even explained the first peak (1 aromatic H atom found). (S)he now wished to explain what fragment caused the peak at 4.8 PPM, but failed on the first attempt (nitrogen-bound -CH2) and now even the second attempt (the aldehyde fragment) as well.
Note that this student isn't that serious with the program, or hasn't been paying that much attention in classes; his credits are almost gone...
The mass spectrum; the end stage of the assignment. The student has explained the molecular cation peak already, and now tried to explain the peak with M/Z 89. But: peak 116 (which generates the start of this peak) has not yet been solved.
