Interactivity, learning goals

Chemistry is a broad area of study covering everything from the basic parts of an Learning Goal atom to interactions between huge biological molecules. Because of this, chemistry encompasses the following specialties. 

Learning Goal Physical properties of liquids, such as those discussed in the previous section, can be explained in terms of their intermolecular forces. We have seen (see Section 4.5) that attractive forces between polar molecules, dipole-dipole interactions, significantly decrease vapor pressure and increase the boiling point. However, nonpolar substances can exist as liquids as well many are liquids and even solids at room temperature. What is the nature of the attractive forces in these nonpolar compoimds ...

Analysis of biomolecular EPR spectra with interaction can be complicated the number of formally required parameters can be so large as to preclude finding a unique solution. The goal of this chapter is to learn how to read interaction spectra in a semiquantitative manner, at best, and to be able to decide what information can be extracted without laborious in-depth analysis, or even to make the interaction altogether disappear by simple physical-chemical means. 

The goal of this chapter is to help you learn about intermolecular forces. Intermolecular forces are interactions between atoms, molecules, and/or ions. We can use these forces to explain both macroscopic and microscopic properties of matter. 

The second article also deals with PET in arranged media, however, this time by discussing comprehensively the various types of heterogeneous devices which may control supramolecular interactions and consequently chemical reactions. Before turning to such applications, photosynthetic model systems, mainly of the triad type, are dealt with in the third contribution. Here, the natural photosynthetic electron transfer process is briefly discussed as far as it is needed as a basis for the main part, namely the description of artificial multicomponent molecules for mimicking photosynthesis. In addition to the goal to learn more about natural photosynthetic energy conversion, these model systems may also have applications, which, for example, lie in the construction of electronic devices at the molecular level. 

In the second situation, using HCS after a traditional HTS campaign, our ability to sift through a list of hundreds to thousands of primary hits rapidly is critical. In this case, the goal should be to determine the compounds that truly interact with the target and filter out those that appear to interact but are really false positives because of cytotoxicity, micelle formation, lack of specificity, etc. If we can also determine which compounds have attractive drug-like structures at the same time, so much the better. This is where HCS often comes in, since we can learn about toxicity, efficacy, and mode of action simultaneously. This added information often more than makes up for the speed and difficulty of HCS. 

Although there have been several studies of chemisorption of certain molecules of interest, there are fewer studies of co-adsorption. This possibly arises from the increasing complexities of controlling coverage in situations where competitive adsorption may exclude or alter the coverage of the reactants. The goal of co-adsorption studies is to learn about interactions between surface coadsorbates, a subject of obvious importance to their catalytic reaction. It is especially of interest from the view of emission control catalysis to study coadsorption of an oxidant and a reductant.
