✦ Synopsis

The two most spectacular host‐guest complexes of recent times are reported here: 1. Cram et al. have successfully synthesized unsubstituted cyclobutadiene in a hemicarcerand at room temperature. This combines the chemists' desire for measurable amounts of highly reactive molecules with that of being able to investigate the molecule, disturbed as little as possible by chemical stabilization. 2. Schwarz et al. have been able to produce complexes of C‐ and C‐fullerene and helium mass spectrometrically; on the basis of several findings, the helium atom in these complexes must be located in the cage. This success could have an enormous stimulating influence on the endohedral chemistry of the fullerenes.

## Abstract We will review recent advances in the investigation of optical modes in single three‐dimensional whispering‐gallery microcavities and coupled microresonators. Due to the small size and high quality factor these resonators have the potential for development of single‐photon emitters, nan

Classical trajectories are calculated on model surfaces designed to reproduce the reactive-unreactive bands found with the SShlK and Yates-Lester surfaces for the H + Hz system cmd other A f BC systems. The model surfaces are based on a rectiIinear reaction path, with a constant period of vibration,
