Question

Can infrared spectroscopy be used to determine whether the
structure of the I3‒ ion is linear or bent? Explain your
reasoning.

Answer #1

yes, the infrared spectroscopy can be used to determine the structure of I3- ions is linear or bent.

The main criteria for IR spectroscopy is that the molecule must generate dipolemoment due to stretching and bending vibration. Assymmetric stretching and bending of I3- ions generate dipole moment, which is responsible to produce vibration peak in IR spectra at different wavelength. This is due to the different value of force constant at two different geometry.

Identify 3 criteria that can be used to determine whether a
logistics organisational structure should be centralised or
decentralised.

1. The combination of infrared (IR) and Raman spectroscopies
constitutes the field of vibrational spectroscopy, which is a
powerful tool in analyzing molecular structure. Let us consider the
vibrational spectroscopy of XY2. Let us propose that
there are four candidate structures for XY2. I. Bent,
with X central, but the X-Y bonds of different length
(Cs symmetry); II. Bent, symmetric, with X central
(C2v symmetry); III Linear, with X central
(D∞h); IV. Linear with Y central (C∞v).
