in an IR explanation in cyclohexanol there are CH2 groups in the ring and that in the IR spectrum was at about v= 1454cm-1 so how will I say that will I say a sharrp, strond band at v=1454cm-1 which illustrates v(C-H) bend of the CH2 groups of cyclohexanol or a strong band at v=1454cm-111 which illustrates v(CH2) of cyclohexanol????
My experience is that the C-H bending at 1454 cm^-1 is not all that strong nor all that sharp; however, these are personal calls and it varies, I suppose, with both the amount of sample and the operator so you call it like it is. I would say ......v = 1454 cm^-1 due to C-H bending of the CH2 groups of cyclohexanol.
By the way, is you used caps for the beginning of a sentence and periods or ?? for the end of a sentence it certainly would improve the readability of your question.
To properly describe the IR spectrum of cyclohexanol, you should say: "A strong band at v=1454 cm-1 which illustrates the v(C-H) bend of the CH2 groups of cyclohexanol."
Explanation: In infrared (IR) spectroscopy, the absorption frequencies are measured in wavenumbers (cm-1). The absorption band at v=1454 cm-1 indicates a specific vibration that is occurring in the molecule. In this case, the v(C-H) bend of the CH2 groups in cyclohexanol is causing the absorption.
It is important to note that the v(CH2) terminology is not commonly used in IR spectroscopy. Instead, we describe the vibrations by the bonds involved, like v(C-H). This provides a precise indication of the specific functional groups present in the molecule.
So, in summary, you should say "a strong band at v=1454 cm-1 which illustrates the v(C-H) bend of the CH2 groups of cyclohexanol."
