As we considered in the class conjugation is generally more effective in the para position than meta. Consider two electron-donating groups: -NH2 and -OCH3. For -OCH3 group spara and smeta values are to -0.29 and 0.11, respectively. For amino group, however, spara = -0.62 and smeta = 0.00. Explain the following observations below. Draw the structures to support your answer. a) Why is smeta value more positive than spara? b) How would you explain smeta = 0.00 for -NH2 group?

Mathematical models of physical phenomena are infinitely precise. However, we are not able to make measurements of physical phenomena with anywhere near that precision. Therefore, we often must “fit” the data we measure to a mathematical model we construct to describe the system. How well the data "fits" helps us understand how good our model is and how well our data collection systems perform. Using the velocity and position data for a falling object provided by the instructor, do the...

1. Explain why an indirect bandgap semiconductor is not considered “good” optical semiconductor. 2. Explain why a direct bandgap semiconductor is considered a “good” optical semiconductor. 3. Explain what a phonon is and explain why they are important for electron transitions between conduction and valence bands in indirect bandgap semiconductors. 4. Explain what is meant by a “radiative transition” and a “non-radiative transition” in semiconductors.
