Rotational Analysis of the ν7 Band in Furan (C4H4O)

Ab initio and matrix isolation study of the acetylene–furan dimer

“…Detailed studies of the gas phase spectra of the furan monomer were performed by Mellouki et al [72][73][74] and Pankoke et al [75]. As expected, the frequencies measured in solid argon are slightly red shifted, by 0.5-3 cm À1 compared to the gas phase data.…”

High resolution synchrotron-based study and analysis of the ν14 band of thiophene

“…They assigned $2200 transitions in the P-and R-branches and their analysis yielded both the ground state and excited state rotational constants as well as centrifugal and sextic distortion parameters. By comparison, the nitrogen and oxygen-containing analogs of thiophene (known as pyrrole and furan, respectively) have been the subjects of more extensive high resolution spectroscopic studies [9][10][11][12][13][14][15]. This is likely a consequence of their less dense rotational structures which are more amenable to assignment and analysis.…”

Synthesis of allyl end‐block functionalized poly(ε‐caprolactone)s and their facile post‐functionalization via thiol–ene reaction

“…With increasing the functionalization degree, the intensity of the absorption signal corresponding to double bonds at 3079 cm −1 decreases . Concurrently, the intensities of the signals corresponding to furan groups at 3146, 3117 và 1011 cm −1 increase …”
