Nikhil Guchhait,Sudip Banerjee,Avijit Chakraborty,Debnarayan Nath,Ganpathi Patwari Naresh,Mihir Chowdhury +5 more
TL;DR: The hydrated clusters of tetrahydroisoquinoline have been investigated by laser-induced fluorescence, UV-UV hole burning, and IR-UV double-resonance spectroscopy in a seeded supersonic jet and it is found that the water molecules form linear and eight-membered cyclic H-bonded structures at the nitrogen center of 1:1, 1:2, and 1:3 clusters.

Jaan Laane,R. C. Lord +1 more
TL;DR: The infrared spectrum of cyclopentene has been recorded in the range 18-300 cm−1 as mentioned in this paper, and two series of thirteen and nine Q branches, respectively, were observed, both of which arise from the strongly anharmonic energy levels of the B1 ring puckering vibration.
