THEORY
OF
SPECIFIC
HEAT
[22]
related
the
infrared proper
frequencies
to
oscillations
of
atoms
(atom
ions)
and
the
ultraviolet
proper
frequencies
to the
oscillations
of
electrons.
This
poses
a
second
significant
difficulty
for
the
molecular-kinetic
theory
of
heat,
because the specific
heat
would
have
to
exceed
significantly
the
value
5.94
n,
since the
number
of
mobile
mass
points per
molecule
is larger than the
latter's
number
of
atoms.
Based
on
the above
one
should
note here
the
following:
If
we
conceive
of the
carriers
of heat
in
solids
as
periodically
oscillating
structures whose
frequency
is
independent
of
their
oscillation
energy,
then
according
to
Planck's
theory
of
radiation
we
should not
expect
the
value
of the
specific
heat
always
to
be
5.94
n.
Rather,
we
have
to set (7)

The energy

such

hence has

heat the value
