UV-visible absorption spectroscopy probes electronic transitions due to electronic excited states, where as absorption of IR radiation excites molecular vibrations and no electronic excited states. However, UV-visible radiation can also excite the molecular vibrations as well, and so what is observed is the superposition of the electronic absorption in addition to the vibrational absorption spectra. IR spectra are broadened by molecular rotations, which are caused by the absorption of lower energy microwave radiation (and rotational spectra can be extremely sharp).
If the species you are probing are atoms only, than they do not have any vibrations (because there are no bonds) and so the UV-visible spectra of atoms is very sharp.

Land with a broad base that rises sharply into a peak from the land around it?
A mountain is a land form with a broad base that rises sharply into a peak. It is a large natural elevation of the surface of the Earth.
What is the traditional method of infrared spectroscopy?
Infrared spectroscopy (IR spectroscopy) is the subset of spectroscopy that deals with the infrared region of the electromagnetic spectrum. It covers a range of techniques, with the most common type by far being a form of absorption spectroscopy. As with all spectroscopic techniques, it can be used to identify a compound and to investigate the composition of a sample. For further details, see the links to the left of this answer.
What effect would it have on the chromatogram with a broad sample?
A broad sample would result in peak broadening on the chromatogram. This can be caused by factors such as sample dispersion, slow diffusion rates, or poor column efficiency. Broad peaks can lead to decreased resolution and difficulty in accurately determining peak parameters.
Which volcanoes are shaped in a sharp peak?
Volcanoes that are shaped with a sharp peak are typically stratovolcanoes, also known as composite volcanoes. Some examples of stratovolcanoes with distinct sharp peaks include Mount Fuji in Japan, Mount St. Helens in the United States, and Mount Kilimanjaro in Tanzania.
What is G band in raman spectroscopy?
The G band in Raman spectroscopy refers to a specific peak observed in the Raman spectrum of carbon materials such as graphene and carbon nanotubes. It corresponds to the in-plane vibrational motion of carbon atoms in a hexagonal lattice structure, known as the E2g phonon mode. The G band peak provides information about the degree of crystallinity and the sp2 hybridization of carbon atoms in the material.
What is th e sharp intense peak at 1246 cm-1 usually indicative of?
The sharp intense peak at 1246 cm-1 is usually indicative of the presence of an ester functional group in a molecule. Ester functional groups typically exhibit strong absorption in this region due to the C-O stretching vibrations. This peak can be helpful in identifying esters in infrared spectroscopy analysis.
What is a sharp pyramid-shaped peak called?

What is the significance of the photo peak in gamma spectroscopy analysis?
The photo peak in gamma spectroscopy analysis is significant because it represents the energy level of the gamma ray emitted by a specific radioactive source. By identifying and analyzing the photo peak, scientists can determine the type and amount of radioactive material present in a sample, aiding in various applications such as environmental monitoring and nuclear security.
What is the IR peak of SiC using FT IR spectroscopy?
The Si-CH3 peak is typically a strong & sharp peak @ 1250 +/- 10 cm-1. Other examples of silicone peaks are as follows: Si-H (silane) @ 2100-2360 cm-1 and Si-O @ 1000-1110 cm-1 (could have a shoulder).
How tall is Mount Broad Peak?

What information can be obtained from a broad peak in an IR spectrum?
A broad peak in an infrared (IR) spectrum can provide information about the presence of functional groups with hydrogen bonding or multiple types of bonds. It can indicate the presence of molecules such as alcohols, carboxylic acids, or amines.
What is a sharp jagged mountain top called?
The sharp jagged mountain top is called the peak. The very top of the mountain might also be referred to as the summit.
