... Hint: The molecular formula is an integral multiple of empirical formula. That is, the molar mass = empirical molar mass x integer. From C: H = 80.00/12 : 20.00/1 = 6.66: 20 = 1: 3. So the empirical formula is CH3 and the empirical molar mass of CH3 = 12x1+1x3 =15. So the integer = 30/15 = 2. Thus t ...

Rutherford backscattering spectrometry
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
