    Description / Table of Contents: Whether he's discussing how to reconcile economy with ecology, why a warmer world will result in more poison ivy, why Britney Spears gets more hits on Google than global warming does, or why we might need to start eating jellyfish for supper, David Suzuki points the direction we must take as a society if we hope to meet the environmental challenges we face in our still-young century. Covering suburban sprawl, sustainable transportation, food shortages, biodiversity, technology, public policy, and more, The Big Picture not only identifies the problems we face but proposes solid, science-based solutions. These engaging essays look beyond environmental challenges to examine the forces that are preventing real change from occurring. Together they tell the story of a species struggling to come to grips with its own biological nature, a nature we must ultimately embrace to live in balance with the systems that sustain us.

    Notes: We have carried out molecular dynamics simulations on the system of a hydrogen molecule dissolved in water or in heavy water in an attempt to understand the experimental results of Taylor and Strauss [J. Chem. Phys. 90, 768 (1989)] for the rotational Raman spectrum of H2. By extracting from the simulation the time-varying potential felt by the H2 molecule, we have computed linewidths in various theoretical limits: static, adiabatic, and Redfield. A start has been made at the nonadiabatic calculation. H2/water is a system of a quantum rotor in a classical bath, in which there is little separation of time scales. The calculations do produce the correct absolute magnitude of the linewidths without adjustable parameters. However, the details of the observed variation of the widths with J and with the change of H2O to D2O are not reproduced and are discussed.

    Notes: Resonance enhanced multiphoton ionization photoelectron spectra (REMPI-PES) of CO2 were obtained via several Rydberg states. Contrary to expected diagonal Franck–Condon factors, long vibrational progressions were seen in each photoelectron spectrum. The dominant vibration varied with the resonant state. A long progression of two quanta of the asymmetric stretch was observed in the PES through nf resonances, while symmetric stretches were more apparent with the 3p resonances. These results may arise from photoionization occurring during molecular dissociation.
