B
A shift in the absorption wavelength to a longer wavelength in -visible spectroscopy.
C
A shift in the absorption wavelength to a shorter wavelength in -visible spectroscopy.
D
A decrease in the intensity of absorption in -visible spectroscopy due to a change in the environment of a chromophore.

검증된 단계별 안내1
Identify the term 'hyperchromic effect' and understand that it relates to changes in absorption intensity in UV-visible spectroscopy.
Recognize that the hyperchromic effect specifically refers to an increase in the intensity of absorption.
Understand that this effect is due to a change in the environment of a chromophore, which is a part of a molecule responsible for its color.
Differentiate the hyperchromic effect from other effects such as bathochromic (shift to longer wavelength) and hypsochromic (shift to shorter wavelength) effects.
Conclude that the hyperchromic effect is characterized by an increase in absorption intensity, not a shift in wavelength, due to environmental changes around the chromophore.
