Synchrotron-based highest resolution FTIR spectroscopy of chlorobenzene

“…A comparison of the FTIR spectra of the aromatic molecules monodeutero-benzene, 13 C 12 C 5 H 6 [38][39][40], fluorobenzene [33,41] and chlorobenzene, all of C 2v symmetry show similar structures for the out-of-plane modes (c-type bands), but they look completely different with regard to the in-plane modes (a-type bands). The complicated band structure of fluorobenzene around 800 cm À1 is missing for chlorobenzene.…”

“…Our analysis of chlorobenzene's FTIR spectrum is a further extension of our project to understand the dynamics and spectroscopy of aromatic systems. Compared to the complicated FTIR spectra of fluorobenzene [33,41], pyridine [50], pyrimidine [64], indole, naphthalene [3], azulene [8] and phenol [7] the chlorobenzene spectra are relatively easy to understand as long as the lines are resolved. No complicated resonance features have been detected.…”

“…The vibrational spectrum of chlorobenzene (C 6 H 5 Cl) was assigned in [34][35][36][37]. Although benzene and monodeutero benzene have been studied at high resolution, including work from our group [38][39][40] and recent progress has been made in the analysis of the substituted aromatic molecules phenol [7] and fluorobenzene [33,41], there existed so far only one rovibrational analysis of the m 19a band of chlorobenzene from [42] using diode laser jet spectroscopy. The vibrational ground state has been analyzed using submm wave spectroscopy in [43].…”

High resolution GHz and THz (FTIR) spectroscopy and theory of parity violation and tunneling for 1,2-dithiine (C4H4S2) as a candidate for measuring the parity violating energy difference between enantiomers of chiral molecules

“…The shape of the b-type series is very similar to the shape of the b-type series assigned in the n 15 fundamental of fluorobenzene. 130 However, due to the C 2v symmetry of fluorobenzene the n 15 fundamental shows no c-type transition and therefore no visible Q branch. The n 17 band was chosen to be analyzed first, as a series of regularly spaced spectral patterns can be identified even through preliminary visual inspection.…”

Study and Simulation of a Sensor Based on 2D Photonic Crystals for the Detection of Aromatic Compounds: C6H5I, C6H5F and C6H5Cl

“…In this article, we will use the Channel Drop Filter (CDF) design based on a new 2D photonic crystal-based ring resonator setup to build a new sensor to detect three aromatic compounds C6H5I, C6H5F and C6H5Cl from the benzene family (see Figure 1) [31][32][33].…”
