13C-13C 1,1-INADEQUATE experiments offer a similar look to a 1H-1H COSY experiment. However, the INADEQUATE experiments do not have diagonal and off-diagonal peaks.
The 13C-13C 1,1-INADEQUATE spectrum below shows 10 carbon atoms labeled C1 to C10. The pink lines connect the adjacent C atoms. There are 3 endpoints to the pink lines at C8, C9 and C10. Therefore, there are 3 terminal carbons present.
The connections are:
1. -C1-C2-C7-C4-C5-C3-C1- forming a 6-membered ring system,
2. -C5-C8 leading to a terminal C8 carbon,
3. -C6-C9 leading to a terminal C9 carbon, and
4. -C6-C10 leading to a terminal C10 carbon.
