What factors govern the position of an ir absorption peak? select one or more correct answers.

a. strength of the bond
b. effect of a magnetic field on nucleus spin
c. masses of the atoms involved in the bond
d. the type of vibration being observed

The factors that govern the position of an IR absorption peak includes:

A.)strength of the bond

C.)masses of the atoms involved in the bond

D.)the type of vibration being observed

Explanation:

Infra red spectroscopy covers a range of techniques, mostly based on absorption spectroscopy.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
