Using spectroscopic measurements, what physical process is being observed?

Symmetry can sometimes be used to interpret an NMR spectrum, , and also The above treatment will tell you HOW many signals you should see in the spectrum; it...

Think of the splitting of the lines as two sine waves. They are 180 degrees out of phase because when Star A moves toward Earth making a blue shift, the...

Excellent discussion and graphics here: The term spectroscopic parallax is a misnomer as it actually has nothing to do with parallax. It is, however, a way to find the...

As we know the stars as viewed from the earth are not seen as in their actual position due to atmospheric refraction.But in this method we calculate the distance to...

Stellar parallax on Earth is performed by measuring the position of an object and then measuring it again 6 months later when is at the opposite side of its orbit....

Evolution of complex animals like horses or felines takes millions upon millions of years. You canusually only track it with fossils. ? Sometimes less than two weeks. Maybe shorter. Shortest...

Stars are formed when a cloud of gasses, mainly hydrogen, collapse due to gravity. As more and more gas accumulates the temperature rises. The temperature creates an outward thermal pressure....

nighttime represents the lowest evaporation rate in many dry climates, so CAM plants open their stomata to exchange gases at night in order to minimizewater loss. They close their stomata...

$color(red)"The basic terms"$ Oxidation and reduction is about the transfer of electrons: oxidation = a molecule loses electrons reduction = a molecule gains electrons $color(red)"Electron carriers in cellular...

Bone measurements especially the femur, vary from each individual. The Stapes is usually around 0.25-0.33 cm. (Just convert it to the English system because I'm used to the metric one)
