WebAbstract. Simulating NMR experiments may appear mysterious and even daunting for those who are new to the field. Yet, broken down into pieces, the process may turn out to be easier than expected. Quite the opposite, it is in fact a powerful and playful means to get insights into the spin dynamics of NMR experiments. In this tutorial paper, we show step … WebThe moon was rapidly spinning billions of years ago when it was first formed. Over millions and billions of years, the earth slowly but surely deformed the moon into a sort of oblonge, footballish shape. Planetary objects are not rigid bodies. The Earth is not exactly a sphere either. The Earth attracts the closest bulge on the moon.
