Cover Picture: Laser Spectroscopic Study of Cold Host–Guest Complexes of Crown Ethers in the Gas Phase (ChemPhysChem 4/2013)
The mechanism of molecular recognition in host–guest chemistry has been of interest to many researchers. The key issues for the recognition are the relationship of the size of the guest species and the cavity of the host, the flexibility of the guest/host species and the effect of solvent. On p. 649, T. Ebata, T. R. Rizzo et al. review laser spectroscopic studies performed for cold host-guest complexes of crown ethers in the gas phase to unravel such the problems at the molecular level.
