    Time-resolved photoelectron circular dichroism with a temporal resolution of 2.9 fs is used to track the ultrafast electron dynamics following ultraviolet excitation of neutral chiral molecules, which generate chiral currents that exhibit periodic rotation direction reversal.

    We report organic molecules showing both efficient luminescence and near-unity generation yield of excited states with high spin multiplicity, simultaneously supporting a high efficiency of initialization, spin manipulations and light-based readout at room temperature.

    Many aspects of materials chemistry rely on singlet–triplet spin conversion, but spin–vibronic effects are shown to accelerate the process when vibronic coupling causes the quantum-mechanical mixing of spin states.

    Atomic-level imaging of photocurrents in a single molecule is achieved by combining a tunable laser with scanning tunnelling microscopy, revealing how photons turn into electric current via a photoexcited molecule.

    Femtosecond X-ray liquidography is used to track the vibrational wavepacket trajectories of gold atoms in solution, enabling time-resolved observations of the emergence of vibrations and the evolution of the formation of covalent bonds.

    Photoexcited acridine radical catalysts are found to have redox potentials more reducing than lithium, which is attributed to the population of higher-energy doublet excited states via a twisted intramolecular charge-transfer species.

    A blend of two organic molecules excited by a simple LED light source can release the stored excitation energy slowly as ‘long persistent luminescence’ over periods of up to an hour.

    Mapping the frontier-orbital interactions with atom specificity using X-ray laser-based femtosecond-resolution spectroscopy reveals that spin crossover and ligation determine the sub-picosecond excited-state dynamics of a transition-metal complex in solution.

    Do excited molecules relaxing to their ground state pass through a 'seam' connecting the potential energy profiles of the states? Experimental data suggest the answer to this long-standing question is 'yes'. See Letter p. 440
