Detailed studies of the excitation dynamics in photosynthetic pigment-proteins require an
application of a wide range of spectroscopic methods. From the later part of the previous …

We introduce the basic concepts of two-dimensional electronic spectroscopy (2DES) and a
general theoretical framework adopted to calculate, from first principles, the nonlinear …

Numerous linear and non-linear spectroscopic techniques have been developed to
elucidate structural and functional information of complex systems ranging from natural …

Singlet fission, the process of splitting a singlet exciton into two triplet excitons, has been
proposed as a mechanism for improving the efficiency of future photovoltaic devices. In …

Significance: Recent advances in nonlinear optics in neuroscience have focused on using
two ultrafast lasers for activity imaging and optogenetic stimulation. Broadband femtosecond …

Considerable debate surrounds the question of whether or not quantum mechanics plays a
significant, non-trivial role in photosynthetic light harvesting. Many have proposed that …

Stark spectroscopy experiments are widely used to study the properties of molecular
systems, particularly those containing charge-transfer (CT) states. However, due to the small …

With the perspective of future vibronic studies, ab initio calculations of the energies of
vibrational relaxation that follows the processes of singlet or triplet excitation, and positive or …

We report the development of a new spectroscopic scheme, coherent two-dimensional (2D)
electronic spectroelectrochemistry. Conventional 2D electronic spectroscopy has become …

We demonstrate the performance of a dual frequency comb quantum cascade laser (QCL)
spectrometer for the application of vibrational Stark spectroscopy. Measurements performed …
