As light pulses get shorter in time, they correspondingly get broader in frequency. Kobayashi\u00a0et al.<\/em>take advantage of both properties of attosecond pulses to elucidate iodine monobromide (IBr) photodissociation by detecting ultrafast bromine and iodine spectral shifts simultaneously. A preliminary burst of light weakens the I\u2013Br bond. Then, as the atoms fly apart, they reach a configuration where the bond vibration can couple ground and excited electronic states. The broadband probe pulse reveals rapid changes in each atom’s electronic structure at this juncture.<\/p>\n <\/p>\n Science<\/em>, this issue p.\u00a079<\/a><\/p>\n <\/p>\n <\/p>\n (\uc6d0\ubb38: \uc5ec\uae30<\/a>\ub97c \ud074\ub9ad\ud558\uc138\uc694~)<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" As light pulses get shorter in time, they correspondingly get broader in frequency.
