1.Determine the number of vibrational modes of NH3 and how many of those vibrational modes will be IR active.

2.The 56FeH diatomic molecule absorbs infrared light at a 1661 cm-1. Where does the 54FeH diatomic molecule absorb light? Assume that the bond strengths are the same and use the harmonic oscillator model to answer this question.

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).        In each...

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...

2 Equipartition The laws of statistical mechanics lead to a surprising, simple, and useful result — the Equipartition Theorem. In thermal equilibrium, the average energy of every degree of freedom is the same: hEi = 1 /2 kBT. A degree of freedom is a way in which the system can move or store energy. (In this expression and what follows, h· · ·i means the average of the quantity in brackets.) One consequence of this is the physicists’ form of...

Use Python 3.8: Problem Description Many recipes tend to be rather small, producing the fewest number of servings that are really possible with the included ingredients. Sometimes one will want to be able to scale those recipes upwards for serving larger groups. This program's task is to determine how much of each ingredient in a recipe will be required for a target party size. The first inputs to the program will be the recipe itself. Here is an example recipe...

Pandora is the Internet’s most successful subscription radio service. As of June 2013, it had over 200 million registered users (140 million of which access the service via a mobile device) and over 70 million active listeners. Pandora now accounts for more than 70% of all Internet radio listening hours and a 7% share of total U.S. radio listening (both traditional and Internet). At Pandora, users select a genre of music based on a favorite musician, and a computer algorithm...
