experimental techniques which can be used to tell us where the atoms are located in a molecule. Using advanced techniques‚ very complicated structures for proteins‚ enzymes‚ DNA‚ and RNA have been determined. Molecular geometry is associated with the chemistry of vision‚ smell and odors‚ taste‚ drug reactions and enzyme controlled reactions to name a few.

Convertible Bonds A convertible bond is a bond that can be converted into shares of common stock. Therefore‚ these are two sources of value for this security: the value of the bond components‚ and the value from possibly converting the security into shares of common stock. Features of a Convertible Bond The basic features of a convertible bond can be illustrated by a hypothetical example. On November 1‚ 2003 ("today")‚ Apple‚ had $400 million in 8.80 percent (annual payments) convertible bonds due in

Arenes The aromatic hydrocarbons also have the name arenes. They contain in their molecule one or more cycles made up from 6 carbon atoms. When the molecule is formed out of a single cycle‚ the hydrocarbons are mono nucleuses; when the molecule contains more than one cycle‚ the hydrocarbons are poly nucleuses. The simplest aromatic hydrocarbon‚ benzene‚ is compound out of just one such cycle; its formula is C6H6. The representation of benzene through a cycle of 6 carbon atoms with 3 double bounds

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

Chapter 6 Bond Valuation 6.5 Duration and Convexity Problem Given a 4-yr treasury bond with a face value of $1‚000‚ an annual coupon rate of 3.20%‚ which had a yield to maturity of 2.53%‚ this bond makes 2 semi-annual coupon payments. Thus has 8 periods until maturity and we are required to determine what the duration‚ modified duration‚ and convexity of this bond is‚ based on the Annual Percentage Rate (APR) and the Effective Annual Rate (EAR). Also‚ we are asked to explain an intuitive interpretation
