Eclipsed conformation. In chemistry an eclipsed conformation is a conformation in which two substituents X and Y on adjacent atoms A, B are in closest proximity, implying that the torsion angle X–A–B–Y is 0°. [1] Such a conformation can exist in any open chain, single chemical bond connecting two sp 3 - hybridised atoms, and it is ...
Conformational isomerism. Rotation about single bond of butane to interconvert one conformation to another. The gauche conformation on the right is a conformer, while the eclipsed conformation on the left is a transition state between conformers.

In astronomy, a syzygy (/ ˈsɪzədʒi / SIZ-ə-jee; from Ancient Greek συζυγία (suzugía) 'union, yoke') [1] is a roughly straight-line configuration of three or more celestial bodies in a gravitational system. [2] The word is often used in reference to the Sun, Earth, and either the Moon or a planet, where the latter is in conjunction ...
Eclipse (software) Eclipse is an integrated development environment (IDE) used in computer programming. [5] It contains a base workspace and an extensible plug-in system for customizing the environment. It is the second-most-popular IDE for Java development, and, until 2016, was the most popular. [6]
Sun-Moon configurations that produce a total (A), annular (B), and partial (C) solar eclipse. A total eclipse occurs when the observer is within the umbra, an annular eclipse when the observer is within the antumbra, and a partial eclipse when the observer is within the penumbra. During a lunar eclipse only the umbra and penumbra are applicable ...
t. e. An integrated development environment (IDE) is a software application that provides comprehensive facilities for software development. An IDE normally consists of at least a source-code editor, build automation tools, and a debugger. Some IDEs, such as IntelliJ IDEA, Eclipse and Lazarus contain the necessary compiler, interpreter or both ...
The solar eclipse configuration is also important: when it occurs near sunrise or sunset or even below the horizon, the lunar shadow is extremely elongated from one side of the sky to the other. The section of the sky that is in shadow automatically reduces the contrast [ citation needed ] with the far-off horizon, making it hard to distinguish.
e. Jakarta EE, formerly Java Platform, Enterprise Edition (Java EE) and Java 2 Platform, Enterprise Edition (J2EE), is a set of specifications, extending Java SE [1] with specifications for enterprise features such as distributed computing and web services. [2] Jakarta EE applications are run on reference runtimes, which can be microservices or ...
