Question

The microwave spectrum of ^{39}K^{127}I consists
of a series of lines whose spacing is almost constant at 3634 MHz.
Calculate the bond length of ^{39}K^{127}I.

Answer #1

Everything is taken in cgs units.

The microwave spectrum of the 12C16O molecule consists of a
series of lines separated by 3.913 cm−1. Draw the corresponding
energy level diagram for this spectral line spacing for the first 5
energy levels, assuming the rigid rotor model. Give the value for
the energy gap between each level.

the microwave spectrum of (39)K(127)I consists of
lines spaced by 3634 MHz. what it's the bond length of this
molecule? I know i need to find the reduced mass would i then plug
that into v= 1/2pi sqrt(k/reduced mass) and solve for k? and after
that not sure where to go to solve for bond length, please help

One series of lines in the hydrogen spectrum is caused by
emission of energy accompanying the fall of an electron from outer
shells to the fourth shell. The lines can be calculated using the
Balmer-Rydberg equation:
1λ=R∞[1m2−1n2]
where m=4, R∞ = 1.097×10−2nm−1, and nis an
integer greater than 4.
Part A
Calculate the wavelengths in nanometers of the first two lines
in the series.
Express your answers using four significant figures separated by
a comma.
Part B
Calculate the energies...

Atomic hydrogen produces a well-known series of spectral lines
in several regions of the electromagnetic spectrum. Each series
fits the Rydberg equation with its own particular n1
value. Calculate the value of n1 that would
produce a series of lines in which the highest energy line has a
wavelength of 365 nm.

The first two anti-Stokes lines in the rotational Raman spectrum
of N2 occur at 29709.1 and 29717.1 cm-1.
Calculate the bond length of N2 molecule.

The absorption spectrum is the characteristic pattern of dark
lines or bands that occurs when electromagnetic radiation is passed
through a medium into a spectroscope. Suppose radiation with a
continuous spectrum is shined on a gas of hydrogen gas whose atoms
are all in the ground state, which spectral series will be missing
in the resulting absorption spectrum?

Two of the adjacent absorption lines in the pure rotational
spectrum of 23Na81Br occur at 3.623 and 3.92 cm-1 . Assuming
23Na81Br behaves as a rigid rotor:
i) Calculate the moment of inertia for this molecule.
ii) Calculate the bond length of 23Na81Br.
iii) Determine the most intense transition in the rotational
spectrum of 23Na81Br if the measurement is carried out at 25oC.

The rigid rotor model assumes that the molecular bond does not
stretch during rotation. Describe...

there is a brackett series in the hydrogen spectrum where n1=4.
Calculate the wavelengths in nm of the first two lines of this
series

(b). Determine the (i) longest and (ii) shortest wavelength
lines (in nanometers) in the Paschen series of the hydrogen
spectrum. In which region of the spectrum is the shortest-
wavelength line? (c) Using the Balmer-Rydberg equation, calculate
the value of n corresponding to the violet emission line
(wavelength = 434.0 nm) in the Balmer series of the hydrogen
emission spectrum.

1. Calculate the difference in energy between the second and
third lines in the Paschen series ofhydrogen’s emission
spectrum.
2. The half-life of americium-243 is7.37×103years. If there

zero(0BCE=0CE,or0BC=0ADifyouprefer), how many are lefttoday?
3.Calculate the approximate density of the unstable
americium-243 nucleus.
