The IR spectrum of benzene and benzene dimer embedded in superfluid helium droplets in the region of the C–H stretch vibration (3000–3110cm-1) was observed. By analyzing the pressure dependence of the spectra it was possible to assign these spectra to benzene monomer and dimer. Based on ...
What makes an OH group stretch broad on an IR spectrum? Explain the difference between K_P and K_c. When is each used? Is basin of water equivalent to basin of ice, why or why not? Explain in your own words. Describe the similarities and differences between cubic close-packed and...
Compared to the c-C22O22 results, 𝐷2ℎD2h c-Si22O22 has two intensities larger than that corresponding to water’s 70 km mol−1−1 antisymmetric stretch. These c-Si22O22 intensities are the highly intense 496 km mol−1−1 at 814.4 cm−1−1 for the 𝜈2ν2 lateral ...
Results. The shapes and the relative intensities of the bands centered at ~3.25 and 3.40 µm and assigned to the C–H stretch of sp2 and sp3 carbon atoms, respectively, present a clear dependence on the nH/nC ratio. From a comparison with the astronomical spectrum from the Orion bar H2S...
In this work, high resolution Fourier transform infra-red (IR) spectrum corresponding to the weak overtone C O stretch band of methanol-D3 (CD3OH) has been recorded at a resolution of 0.004 cm1, in the range 1882–2012 cm1. The spectrum has the typical appearance of a ΔK=0 spectrum ...
