## Abstract The ^13^C NMR chemical shifts of (4aα,8aα, 9aβ, 10aα)‐, (4aα,8aα,9aα, 10aβ)‐ and (4aα,8aβ,9aα, 10aβ)‐tetradecahydroacridine were measured and fully assigned on the basis of APT, ^13^C, ^1^H shift correlation and 2D‐INADEQUATE spectra.

## Abstract ^13^C NMR signals were assigned for 18 methyl 5β‐cholenoates with a double bond in ring A, B, C or D (Δ^2^, Δ^3^, Δ^5^, Δ^6^, Δ^7^, Δ^8(14)^, Δ^9(11)^, Δ^11^ or Δ^14^). The double bond substituent effects on the ^13^C NMR chemical shifts of the parent 5β‐cholanoates were clarified.
## Abstract Carbon‐13 chemical shifts of three arylmethyl carbanions have been determined by changing solvents and counter ions. The charge distributions in the carbanions are discussed and compared with those obtained from the ^1^H chemical shifts.
