Two-photon excitation of fluorescent proteins is an attractive approach for imaging living
systems. Today researchers are eager to know which proteins are the brightest and what the …

The activity within a living cell is based on a complex network of interactions among
biomolecules, exchanging information and energy through biochemical processes. These …

We investigate the performance of CC2 and TDDFT/CAM-B3LYP for the calculation of two-
photon absorption (TPA) strengths and cross sections and contrast our results to a recent …

Fluorescent proteins with long emission wavelengths are particularly attractive for deep
tissue two-photon microscopy. Surprisingly, little is known about their two-photon absorption …

A comprehensive vibronic coupling model based on the time-dependent wavepacket
approach is derived to simulate linear optical processes, such as one-photon absorbance …

The equation-of-motion coupled-cluster (EOM-CC) methods provide a robust description of
electronically excited states and their properties. Here, we present a formalism for two …

The use of two-photon absorption (TPA) for such applications as microscopy, imaging, and
photodynamic therapy (PDT) offers several advantages over the usual one-photon …

We present for the first time a QM/MM study of the one-and two-photon absorption spectra of
the GFP chromophore embedded in the full protein environment described by an advanced …

We report calculations of one and two photon absorption (OPA and TPA, respectively)
spectra of the green fluorescent protein (GFP) chromophore using the double-harmonic …

Performance of DFT functionals with different percentages of exact Hartree–Fock exchange
energy (EX) is assessed for recovery of the CC2 reference one-(OPA) and two-photon …
