Cremer and Pople

In cyclohexane there are three puckering modes described by the generalized coordinates q2, q3, and . Cremer and Pople [1975a,b] introduced the amplitude Q q2 = Q sin 0, q3 = Q cos 0) to portray the set of conformers in spherical coordinates (Figure 8.9). The axial conformer C (6 = 0°, 180°) has a chair-like shape. Transverse displace-... [Pg.280]

Figure 8.9. One octant of a sphere on which the conformations of cyclohexane can be mapped. Special conformations C, chair B, boat TB, twist boat HB, half-boat and HC, half-chair.

These are the well-known puckering parameters first defined by Cremer and Pople [205]. [Pg.223]

A stereographic spherical representation of the conformational itinerary of carbohydrates using Cremer and Pople puckering parameters has been published. ... [Pg.200]
