The dipeptide cyclic(glycyltryptophanyl) in the gas phase: A concerted action of density functional calculations, S₀–S₁two-photon ionization, spectral UV/UV hole burning and laser photoelectron spectroscopy

Isolated Neutral Peptides

“…It has quickly been extended to other species, beyond the simple canonical structures. Short cyclic peptides have been investigated, documenting the cis conformation of the peptide bonds [76,78,129], which is usually too high in energy to be observed in linear peptides. More recently, other peptides, with longer spacers between amide bonds, i.e.…”

Rotationally resolved electronic spectroscopy of 5-methoxyindole

“…24 In brief, the sample molecules were heated to 110°C to form a suitable partial pressure in a pulsed valve ͑General Valve, Iota One͒ operated at 10 Hz with 4 bar Ar as a carrier gas. 24 In brief, the sample molecules were heated to 110°C to form a suitable partial pressure in a pulsed valve ͑General Valve, Iota One͒ operated at 10 Hz with 4 bar Ar as a carrier gas.…”

Resonance Two-Photon Ionization of Diarylethene in the Presence of Cyclodextrin

“…These materials are expected to find uses in various applications, such as in memory devices in the IT field, as sensor materials for light modulation, or in the industrial field as well as in textile products (printed shirts). Due to the poor solubility of this DE in water, we used the inclusion effect of cyclodextrins (CDs) to dissolve it in water, after which we investigated its photoionization properties [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], which is a type of photolysis. The photochromic behavior of diarylethene derivatives attached to CD and dissolved in water has been reported to influence the quantum yield of the transformation from an open to a closed structure [17,18].…”
