High School What region in NMR spectrum should I choose for integration?

Click For Summary
Choosing the correct region for integration in a nuclear magnetic resonance (NMR) spectrum depends on the specific analytical goals. The intensity of peaks and their corresponding regions must align with the information needed for interpretation. Users should consider the chemical environment and the number of protons contributing to each peak when deciding between region 1 or region 2. Proper integration will yield more accurate quantitative data relevant to the analysis. Ultimately, the integration region should be selected based on the desired outcome of the spectral analysis.

What region in NMR spectrum should I choose for integration?
Hi all,
I have nuclear magnetic resonance spectrum. The vertical axis is intensity, and the horizontal axis is index. I need to find integral under the peak. But I am not sure, what region should I choose for integration - region 1 or region 2? Please find attached the spectrum.

That depends on what exact question you're trying to answer by integrating the spectrum.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
