X-ray absorption spectroscopy on attosecond and femtosecond timescales is a frontier of modern ultrafast science. For the last two decades, ultrafast lasers produced ever growing powers that facilitate implementation of attosecond high-harmonic soft X-ray sources in compact equipment. This unique broad-band light source opens the door for numerous applications; in particular it is ideal for chemical dynamics studies due to its sensitivity to electronic and vibrational state changes. Here, we outline briefly the evolution of time-resolved technology and review several case studies in which extreme ultraviolet and soft X-ray spectroscopy prove its exclusive sensitivity to the electronic structure of molecular species.
