The spectrum observed at 243 K from the sample

The spectrum obtained by Fourier transforming , -truncated data, -----Blackman window,. maximum entropy.

The spectrum obtained from sample A after it has been heated to 200 C showing more clearly the distortion in the middle of the dating signal .

The spectrum of a cascade-type of sound

The spectrum of a cast film of predominately

The spectrum of a conventional metal porphyrin in the visible and ultra-violet regions

The spectrum of a high-spin, Fe haemoprotein, cyanide myoglobin

The spectrum of a melos sound

The spectrum of a photochemical hole burned in the long-waveloigth absorption band of a sample of photosynthetic bacterial reaction centers at 5 K . The gray curve is the difference between absorption spectra measured with the excitation laser on and off. The excitation frequency was 10,912 cm. Note the sharp zero-phonon hole PH, upward arrow at 10,980 cm . The downward arrows indicate the centers of two discrete vibrational bands that are linked to the zero-phonon transition. The solid curve is a theoretical hole spectrum calculated as described in the text

The spectrum of a pulse waveform has both odd and even harmonics

The spectrum of a rotator in the truncated basis

The spectrum of a single molecule .

The spectrum of ammonium nitrate in DMSO , the Nlli ion dominates and the induced symmetry reduces the quadrupolar relaxation rate and reveals the one-bond

The spectrum of an explosive metallic sound

The spectrum of an FM sound is composed of the offset carrier frequency and a number of partiais on eifher side of if, spaced at a distance equal to the modulator frequency

The spectrum of approaches to finding chemical tools or leads, illustrating the inverse relationship between information content and number of compounds needed.

The spectrum of bacterial luminescence measured with B. harveyi luciferase, FMN, tetradecanal and NADH, in 50 mM phosphate buffer, pH 7.0, at 0 C . LumP is a lumazine protein, and Rf-LumP contains riboflavin instead of lumazine in the lumazine protein. Fluorescence emission curves are at the right side of the absorption curves.

The spectrum of biomass pretreated with 1 H2SO4 contains signals from both native cellulose and lignin . Subtraction of a lignin spectrum provides a spectrum of native cellulose which can provide the crystalline index by focusing on the crystalline signal at 88 ppm and on the amorphous signal at 84 ppm. Data were acquired at 9.4 T using a 14 kHz spinning frequency. Reproduced from Bemardinelli et al. published under the CC-BY license.

The spectrum of chemical and biological agents

The spectrum of chloroform with normal decoupling to achieve only the NOE. Reproduced with permission from A. E. Derome,

The spectrum of copal from Mauritania, with normal and interrupted decoupling.

The spectrum of cutaneous mustard injury as seen on light microscopy extends from superficially intact skin to sloughing of the epidermis, The biopsy was taken at the site of an erosion. The epidermis has sloughed, and the superficial dermis is necrotic. White blood cells have infiltrated the deeper layers of the dermis. Part of an intact hair follicle is seen the epidermis will ultimately regenerate from such structures. Reprinted with permission from Willems JL. Clinical management of mustard gas casualties. Ann Med MilitBelg. 1989 3S

The spectrum of electromagnetic radiation.

The spectrum of electromagnetic radiation. The top line is an energy scale, in units of kilocalories per mole .

The spectrum of electromagnetic waves, showing the relationship between wavelength, frequency, and energy.
