The 2d particle in a box model can be used to describe the spectra of aromatic hydrocarbons. assume a rectangular box that extends one bond length beyond the carbon atonm contain the hydrogen atoms in the box. hint: you wil have to use some trigonometry basics to get the relevant dimensions.
a. calculate the first three electronic transitions for napthalene (bond length 1.42 angstroms)
b. calculate the first three electronic transitions for pyrene (bond length 142 angstroms)

A. is your answer.  hope this  

Answer( precipitate );

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
