Einführung

Anmerkung

Die beobachteten Kopplungen lassen zwei Lösungen zu. Können Sie irgendwie zwischen beiden Lösungen unterscheiden?

Summary

Maybe you should start to analyze the multiplets at 0.8 and 2.6 ppm. What might be hidden behind the apparently trivial multiplet at 1.4 ppm?

Hint

Is there any characteristics for symmetry?

Remark

One part of the substance - and as a consequence two multiplets - is rather common.

Hint

There are a bunch of protons but only two signal groups.

Remark

It's a beginner task. The solution should be not that tricky.

Anmerkung

Die Kopplungskonstanten sind sehr typisch.

Remark

The weak signals at 3 ppm provide a very helpful piece of information. How could the correct signals be separated easily from the signals of impurities with almost the same signal intensity?
