The quantitative description of ring puckering suggested by the authors is compared with that of Cremer and Pople. The applicability of both methods is discussed for the case of six‐membered rings with the use of model calculations simulating various ring distortions and with the analysis and comparison of puckering parameters computed on the basis of x‐ray data for 40 six‐membered rings in different cyclic structures. The 2N times reduction of the field of variation of puckering parameters for the N‐membered ring is suggested and the algorithm for the renumbering of the ring atoms for this purpose is described for six‐membered rings.
