T1  - Precise and rapid detection of optical activity for accumulative femtosecond spectroscopy
JF  - EPJ Web of Conferences
N2  - We present a fast and sensitive polarimeter combining common-path optical heterodyne interferometry and accumulative spectroscopy to detect rotatory power. The sensitivity of rotatory detection is determined to be 0.10 milli-degrees for a measurement time of only one second and an interaction length of 250 µm. Its suitability for femtosecond studies is demonstrated in a non-resonant two-photon photodissociation experiment.

T1  - Exploring higher-lying electronic states of a molecular switch by coherent triggered-exchange 2D electronic spectroscopy
JF  - EPJ Web of Conferences
N2  - We use pump-repump-probe transient absorption spectroscopy to investigate the role of higher-lying electronic states in the photochemistry of a molecular switch. Moreover, replacing the pump pulse by a pulse-shaper-generated phase-stable double pulse, triggered-exchange two-dimensional (TE2D) electronic spectroscopy is established in the visible regime.
