erivatives of the hydrocarbons are formed, by replacing one or more hydrogen atoms by other groups referred to as functional groups An alcohol is closely related to a hydrocarbon in that it contains an Oh group in place of a hydrogen atom. Thus, methyl alcohol, CH3 OH, is a derivative of methane, CH4; and ethyl alcohol

Eco514 Game Theory Lecture 10: Extensive Games with (Almost)Perfect Information Marciano Siniscalchi October 19, 1999 Introduction Beginning with this lecture, we focus our attention on dynamic games. The majority of games of economic interest feature some dynamic component, and most often payoff uncertainty as well. The analysis of extensive games is challenging in several ways. At the most basic level describing the possible sequences of events (choices)which define a particular game form is not problematic per se; yet, different formal definitions have been proposed, each with its pros and cons

Spectroscopy is an analytical technique which helps determine structure. It destroys little or no sample. The amount of light absorbed by the sample is measured as wavelength is varied
