UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.

Estimate the stabilization gained as a result of conjugation when 1,4-pentadiene is converted to trans-1,3-pentadiene. Note that the answer is not as simple as comparing the heats of hydrogenation of 1,4-pentadiene and trans-1,3pentadiene. Although the double bonds are moved from unconjugated to conjugated, the degree of substitution of one of the double bonds is also changed, in this case, from a monosubstituted double bond to a trans disubstituted double bond. To answer this question, you must separate the effect that is the result of conjugation from that caused by a change in the degree of substitution.

I can see that it's correct to have a hydride shift from a secondary carbocation to another secondary carbocation in this case. I guess what I'm saying is, doesn't hydride shifts only occur when it only produces a more stable carbocation? For instance, secondary carbocation does a hydride shift to a tertiary carbocation. Is it correct to do a hydride shift from a secondary carbocation to another secondary carbocation in this case because the pi bond shifts to produce a tertiary carbocation? And this shift (from a secondary carbocation to another secondary carbocation) only plausible if the pi bond shifts afterwards to create the tertiary carbocation?
