Proton and Carbon NMR in Research Paper
Excerpt from Research Paper :
This information is utilized to create new products and substances that are used on a regular basis. For example, chemists could use the COSY process to understand how to create a new kind of raincoat that will be even more water resistant. To determine this, the protons inside the molecules of the raincoat would have to be examined through the COSY process. This will identify the peaks inside the protons and what specific attributes are similar to other compounds. Once this happens, is when scientists can use this as a way to create specific attributes that they are looking for (i.e. A raincoat that is more waterproof). This is significant, because it is showing how the contribution of the COSY methodology allows chemists to create new compounds with specific attributes. ("Thomaston," 2006)
HETCOR is useful in understanding the genetic composition of a substance and the compounds that are used to bond various protons together. This helps researchers to know the way a particular bond is giving a compound its strengths and weaknesses. It is at this point, that new compounds can be added to a molecule to create a new substance. For example, in the field of medicine enzymes are used to combine different kinds of molecules together in creating anti-biotics and other prescription medications. These drugs are designed to deal with specific issues associated with the medical condition of the patient. This is the point that the new compound can begin to address the issues that are impacting the individual. These elements are showing how this basic approach is used to determine the molecular structure and the bonds for different compounds. This helps scientists to create specific substances or products that will address predetermined needs based on select attributes. ("Thomaston," 2006)
Give an Example of a Natural Product whose Structure was Elucidated Using different NMR Techniques.
A natural product that could be a result of different NMR techniques is water. The way that NMR can identify the structure is to look inside the nuclei and show the basic genetic
structure. Scientists can take this information and use it as a way to see how water reacts in different states. The way that 2D NMR can be utilized is to understand how it can be changed. This is accomplished through COSY to learn about specific compounds that can bond with the protons inside the nuclei. While HETCOR, will help chemists to see the specific compounds that are used and if this can be changed. This is when the basic map can be created to change the specific compounds found in nature.
Provide an Explanation of What the Spectra Showed about the Structure
Using the example of water (H20), the spectra showed that it has a number of unique properties to include: strong bonds and a flexible structure. As a result, this is highlighting the basic framework and how the various compounds can be changed. The below table is illustrating the different spectrums for water.
The Spectra for Water
("Nuclear Magnetic Resonance," 2010)
These figures are illustrating how the NMR can identify the genetic structure of water and how it can be changed. This helps in creating products that are using water or involving specific aspects of this substance.
Clearly, the use of NMR techniques is designed to understand the composition of molecules and how they can be changed. As a result, this approach is providing scientists with more specific information about how to achieve these objectives. This means that it is playing a central role in improving knowledge about the atom and the way it would react in a variety of situations.
